CDKN1B gene: MedlinePlus Genetic

• The CDKN1B gene provides instructions for making a protein called p27. This protein is found in cells and tissues throughout the body. Within cells, p27 is located primarily in the nucleus, where it plays a critical role in controlling cell growth and division
• The protein p27 belongs to the family of KIP1 inhibitors, which has a broad spectrum of inhibitory activity on different CDKs and may act as a potential tumor suppressor gene. This protein decreases cyclin-CDK activity and induces cell cycle arrest in cell lines
• the p27 gene rs34330 polymorphism might increase the cancer susceptibility, especially in Asians. our study identified that p27 expression was transcriptionally upregulated by enhancing the binding of FOXO1 to its promoter and post-transcriptionally induced through decreasing binding of miR-182 to its mRNA 3'-UTR upon isorhapontigenin treatment; Cholangiocarcinoma growth is associated with.
• p27 binds and inhibits cyclin-CDK to arrest the cell cycle. p27 also regulates other processes including cell migration and development independent of its cyclin-dependent kinase (CDK) inhibitory action. p27 is an atypical tumor suppressor-deletion or mutational inactivation of the gene encoding p27, CDKN1B , is rare in human cancers. p27 is rarely fully lost in cancers because it can play.
• The p27 gene is located on chromosome 12p13. This protein is bound to cyclin (A, B, D and E)/CDK (1, 2, 4 and 6) and leads to the conformational change of CDK catalytic cleft which ultimately results in the separation of cyclin from the CDK [ 3 ]

2. This gene encodes a cyclin-dependent kinase inhibitor, which shares a limited similarity with CDK inhibitor CDKN1A/p21. The encoded protein binds to and prevents the activation of cyclin E-CDK2 or cyclin D-CDK4 complexes, and thus controls the cell cycle progression at G1

Interestingly, these p27-target genes (p27-TGs) are involved in relevant cellular functions as cell cycle, respiration, translation and mRNA processing and splicing. Expression of p27-TGs was subsequently studied by microarrays in mouse embryonic fibroblasts (MEFs) from control and p27-deficient animals. Results from these studies revealed that p27 mostly behaves as a transcriptional co. CDKN1B, or p27 (KIP1), is a cyclin-dependent kinase inhibitor that blocks the cell cycle in the G0/G1 phase upon differentiation signals or cellular insult. CDKN1B also regulates cell motility and apoptosis (summary by Cuesta et al., 2009). ▼ Cloning and Expressio This gene encodes a potent cyclin-dependent kinase inhibitor. The encoded protein binds to and inhibits the activity of cyclin-cyclin-dependent kinase2 or -cyclin-dependent kinase4 complexes, and thus functions as a regulator of cell cycle progression at G1

Specifically, the changes in p27 protein levels correlated with changes in p27 mRNA levels, and gene transcription. Induction of p27 promoter activity followed BCR engagement of WEHI 231 cells, and.. The MDM2 and p27 genotypes had a significant effect on survival times after treatment (log-rank test, P = 0.010 and P = 0.050, respectively). A strong joint effect of these two genes was observed (log-rank test, P = 0.010) In vivo, Western blotting was performed to check the expression levels of mdig and p27 (KIP1) in human lung cancer tissues, para-cancerous normal lung tissues, and para-bronchial stumps. Knockdown of mdig induced increases in p27 (KIP1), both on mRNA and protein levels (A) CyclinD1 gene expression follows the pattern of Low-High-Low, in response to increasing dose of p27, suggesting that Ccnd1 is highly expressed at the intermediate level of p27 dosage.

• Abstract. Background: The p27 KIP1 gene, whose protein product is a negative regulator of the cell cycle, is a potential tumor suppressor gene; however, no tumor-specific mutations of this gene have been found in humans. This study was undertaken to identify and to assess potential alterations of p27 KIP1 gene expression in patients with benign prostatic hyperplasia (BPH) and patients with.
• In contrast to p27, however, ubiquitination of p21 can take place in the absence of phosphorylation, although with less efficiency (Bornstein et al.,2003). SCF(Skp2)-mediated degradation of p27/p21 continues from late G1 through M-phase. During G0 and from early G1 to G1/S, Skp2 is degraded by the anaphase promoting complex/Cyclosome and its activator Cdh1 [APC/C(Cdh1)] (Bashir et al, 2004.

Abnormal expression of p27 has been reported in a number of highly proliferative human breast cancer cell lines and is thought to play an important role in carcinogenesis.[12-14]To date, only expression of the p27 gene has been investigated in different cancer types.In human breast cancer, low levels of p27 and strong correlation with the apoptotic index have been observed.[]Genomic. Background. The cyclin-dependent kinase inhibitor p27 Kip1 is essential for proper control of cell cycle progression. The levels of p27 Kip1 are regulated by several mechanisms including transcriptional and translational controls. In order to delineate the molecular details of these regulatory mechanisms it is important to identify the transcription initiation site within the p27 Kip1 gene. We previously reported that increased DNA methylation was an important mechanism of silencing the p27 gene in some pituitary tumor cell lines [1]. DNA methylation correlated inversely with p27 gene expression. The p27 and cyclin D2 genes are located in the same region of mouse chromosome 6, rat chromosome 4, and human chromosome 12p13. Because both genes are located in the same gene cluster. Important regulator of cell cycle progression. Inhibits the kinase activity of CDK2 bound to cyclin A, but has little inhibitory activity on CDK2 bound to SPDYA (PubMed:28666995). Involved in G1 arrest. Potent inhibitor of cyclin E- and cyclin A-CDK2 complexes. Forms a complex with cyclin type D-CDK4 complexes and is involved in the assembly, stability, and modulation of CCND1-CDK4 complex.

In an attempt to screen whether that gene region differs in mild and severe strains, six CTV iso-lates belonging to different biogroups were compared for variations in their p27 gene by analysis of single- strand conformation polymorphism (SSCP). The p27 gene was reverse.

Specifically, by knocking down p27, PCAF or both we have seen that PCAF operates as a co-activator and p27 as a repressor and that PCAF is needed for the expression of p27-TGs because in the double knock-down cells gene expression is blocked. Curiously, in this cooperative role each one of these proteins associates to different regulatory sites of the chromatin p27 Kip1. The p27 gene is rarely affected by structural alterations in human malignancies. p27 is a CKI that regulates progression from G 1 into S phase by inhibiting a variety of cyclin-CDK complexes, including cyclin D-CDK4, cyclin E-CDK2, and cyclin A-CDK2. Newcomb et al. showed that p27 expression is positively associated with long-term survival in 66% of patients separated into two equal.

The murine gene p27. Kip1. is haplo-insufficient for tumour suppression. p27 Kip is a candidate human tumour-suppressor protein, because it is able to inhibit cyclin-dependent kinases and block cell proliferation. Abnormally low levels of the p27 protein are frequently found in human carcinomas, and these low levels correlate directly with both. In this issue of Genes & Development, a report by Besson et al. shows the cytoplasmic role of p27 kip1 in promoting cell migration and the absence of a tumor selection for complete loss of p27 kip1 begins to look like a gene living a dual life in cancer, one as a nuclear tumor suppressor and the other as a cytoplasmic metastatic oncogene. Clearly much more work on p27 kip1 is required. Plasmid pGL3-p27 T187A Luc from Dr. William Kaelin's lab contains the insert p27 and is published in Nat Med. 2004 Jun . 10(6):643-8.

In the absence of p27 activity, progenitor cells move into the cell cycle and proliferate; whereas in the absence of p21. However, the p53-regulated p27 gene expression has not been reported before. The finding from our preceding experimental results had indicated that p53 induction could up-regulate p27 promoter activity, which in turn increased the mRNA and protein levels of p27. Moreover, we had found that p53 protein could associate with the p27 DNA. Therefore, the main goal of this proposed research study is. p27 and p21 in gene therapies . United States Patent 8461127 .
