PSIP1 - PC4 and SRSF1 interacting protein 1 Gene
Also Known as p52; p75; PAIP; DFS70; LEDGF; PSIP2
Species: Homo sapiens
About PSIP1
This gene has 11 transcripts (splice variants), 255 orthologues, 4 paralogues and is associated with 66 phenotypes. Ubiquitous expression in brain (RPKM 41.2), ovary (RPKM 33.4) and 24 other tissues.
Summary
Enables DNA-binding transcription factor binding activity; chromatin binding activity; and transcription coactivator activity. Involved in mRNA 5'-splice site recognition and positive regulation of transcription by RNA polymerase II. Located in heterochromatin; nuclear periphery; and nucleoplasm.
