PR domain zinc finger protein 5; PR domain-containing protein 5 (PRDM5, PFM2)

Function: - sequence-specific DNA-binding transcription factor - represses transcription at least in part by recruitment of histone methyltransferase EHMT2/G9A & histone deacetylases such as HDAC1 - regulates hematopoiesis-associated protein-coding & microRNA (miRNA) genes - may regulate the expression of proteins involved in extracellular matrix development & maintenance, including fibrillar collagens, such as COL4A1 & COL11A1, connective tissue components, such as HAPLN1, & molecules regulating cell migration & adhesion, including EDIL3 & TGFB2 - may cause G2/M arrest & apoptosis in cancer cells - interacts with EHMT2/G9A, GFI1 & HDAC1 Structure: - contains 16 C2H2-type Zn+2 fingers - contains 1 SET domain Compartment: nucleus Alternative splicing: named isoforms=3 Expression: - widely expressed - highest levels in colon & ovary - tends to be silenced in breast, colorectal, gastric & liver cancer tissues Pathology: - defects in PRDM5 are the cause of brittle cornea syndrome type 2
