DESCRIPTION

Also known as RBM14_HUMAN, RBM14, SIP. Isoform 1 may function as a nuclear receptor coactivator, enhancing transcription through other coactivators such as NCOA6 and CITED1. Isoform 2, functions as a transcriptional repressor, modulating transcriptional activities of coactivators including isoform 1, NCOA6 and CITED1 (PubMed:11443112). Regulates centriole biogenesis by suppressing the formation of aberrant centriolar protein complexes in the cytoplasm and thus preserving mitotic spindle integrity. Prevents the formation of the STIL-CENPJ complex (which can induce the formation of aberrant centriolar protein complexes) by interfering with the interaction of STIL with CENPJ (PubMed:25385835). Plays a role in the regulation of DNA virus-mediated innate immune response by assembling into the HDP-RNP complex, a complex that serves as a platform for IRF3 phosphorylation and subsequent innate immune response activation through the cGAS-STING pathway (PubMed:28712728). Isoform 1: Interacts with NCOA6, CITED1 and XRCC5/KU86 (PubMed:11443112). Isoform 1: Interacts with SS18 isoform 1 (PubMed:15919756). Isoform 1: Interacts with SS18 isoform 2 (PubMed:15919756). Interacts with STIL and interferes with its interaction with CENPJ. Interacts with gamma-tubulin (PubMed:25385835).Part of the HDP-RNP complex composed of at least HEXIM1, PRKDC, XRCC5, XRCC6, paraspeckle proteins (SFPQ, NONO, PSPC1, RBM14, and MATR3) and NEAT1 RNA.
