This entry represents the PR/SET domain found in PR domain zinc finger protein 5 (PRDM5). PRDM5 is a sequence-specific DNA-binding transcription factor that represses transcription at least in part by recruitment of the histone methyltransferase EHMT2/G9A and histone deacetylases such as HDAC1 []. Mutation of the PRDM5 gene has been linked to Brittle cornea syndrome 2 (BCS2) [].The PRDM family members are characterised by the presence of a N-terminal PR (PRDI-BF1 and RIZ1 homology) domain followed by multiple zinc fingers which confer DNA binding activity. PR domains are only distantly related to the classical SET methyltransferase domains []. They are involved in epigenetic regulation of gene expression through their intrinsic histone methyltransferase activity or via interactions with other chromatin modifying enzymes [].
