Abstract: PRDM protein family which has a PR domain and varying amounts of zinc finger domains (except PRDM11), widely present in primates, rodents, birds and amphibians, involve in regulation of epigenetic proteins.Some PR domains possess transferase activity of histone lysine (HMT), affect epigenetics features and the Zinc finger domains may recognize and bind DNA, RNA, protein;The other PR domains of PRDM without HMT activity, play a key role in carcinogenesis, specification of primordial germ cell, neurogenesis, hematopoiesis, vascular development, and embryonic development.PRDM protein family participate in cell specialization, and disease regulation, regulating gene expression and modifying chromatin structure by methyl transfer, or recruited chromosome structure reshape compounds.This review summarized the latest research progress on structure and function of PRDM protein family.

Key words: PRDM protein family; epigenetics; PR domain; zinc finger; histone lysine transferase activity
