| 23096495    | 2013 | Cell line : - Source : - Sample Type : - No. of Sample : 131 CRC patients Stage : - | Methyl specific PCR and Illumina 27K microarray | Hypermethylation | - | PTPR family has an important role in the etiology of CRC. The analysis of promoter methylation using an Illumina 27K microarray revealed four protein tyrosine phosphatases PTPRM, PTPRT, PTPRR and PTPRZ1 as being hypermethylated with p-value 0.2 and P = 0.05. |

| Description | The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP possesses an extracellular region, a single transmembrane region, and two tandem catalytic domains, and thus represents a receptor-type PTP. The extracellular region contains a meprin-A5 antigen-PTP mu (MAM) domain, an Ig-like domain and four fibronectin type III-like repeats. This PTP has been shown to mediate cell-cell aggregation through the interaction with another molecule of this PTP on an adjacent cell. This PTP can interact with scaffolding protein RACK1/GNB2L1, which may be necessary for the downstream signaling in response to cell-cell adhesion. Alternative splicing results in multiple transcripts encoding distinct isoforms.   | Chromosome | 18 |
