PR-SET domain found in PR domain zinc finger protein 1 (PRDM1) and similar proteins
PRDM1 (also termed BLIMP-1, beta-interferon gene positive regulatory domain I-binding factor, PR domain-containing protein 1, positive regulatory domain I-binding factor 1, PRDI-BF1, or PRDI-binding factor 1) acts as a transcription factor that mediates a transcriptional program in various innate and adaptive immune tissue-resident lymphocyte T cell types such as tissue-resident memory T (Trm), natural killer (trNK) and natural killer T (NKT) cells and negatively regulates gene expression of proteins that promote the egress of tissue-resident T-cell populations from non-lymphoid organs.
