Summary
PHF5A (PHD finger protein 5A, HGNC:18000) is a protein-coding gene on chromosome 22q13.2, encoding PHD finger-like domain-containing protein 5A (Q7RTV0). Component of the 17S U2 SnRNP complex of the spliceosome, a large ribonucleoprotein complex that removes introns from transcribed pre-mRNAs. It is a common-essential gene (DepMap: required in 100.0% of cancer cell lines).
This gene encodes a subunit of the splicing factor 3b protein complex. Splicing factor 3b, together with splicing factor 3a and a 12S RNA unit, forms the U2 small nuclear ribonucleoproteins complex (U2 snRNP). The splicing factor 3b/3a complex binds pre-mRNA upstream of the intron’s branch site in a sequence-independent manner and may anchor the U2 snRNP to the pre-mRNA. The protein encoded by this gene contains a PHD-finger-like domain that is flanked by highly basic N- and C-termini. This protein belongs to the PHD-finger superfamily and may act as a chromatin-associated protein. This gene has several pseudogenes on different chromosomes.

Function. Component of the 17S U2 SnRNP complex of the spliceosome, a large ribonucleoprotein complex that removes introns from transcribed pre-mRNAs. The 17S U2 SnRNP complex (1) directly participates in early spliceosome assembly and (2) mediates recognition of the intron branch site during pre-mRNA splicing by promoting the selection of the pre-mRNA branch-site adenosine, the nucleophile for the first step of splicing. Within the 17S U2 SnRNP complex, PHF5A is part of the SF3B subcomplex, which is required for ‘A’ complex assembly formed by the stable binding of U2 snRNP to the branchpoint sequence in pre-mRNA. Sequence independent binding of SF3A and SF3B subcomplexes upstream of the branch site is essential, it may anchor U2 snRNP to the pre-mRNA. Also acts as a component of the minor spliceosome, which is involved in the splicing of U12-type introns in pre-mRNAs. Also involved in elongation by RNA polymerase II as part of the PAF1 complex (PAF1C). PAF1C is required for maintenance of embryonic stem cell (ESC) self-renewal and cellular reprogramming of stem cells. Maintains pluripotency by recruiting and stabilizing PAF1C on pluripotency genes loci, and by regulating the expression of the pluripotency genes. Regulates the deposition of elongation-associated histone modifications, including dimethylated histone H3 ‘Lys-79’ (H3K79me2) and trimethylated histone H3 ‘Lys-36’ (H3K36me3), on PAF1C targets, self-renewal and pluripotency genes. Regulates RNA polymerase II promoter-proximal pause release of the PAF1C targets and self-renewal genes, and the levels of elongating (‘Ser-2’ phosphorylated) RNA polymerase II in their gene bodies. Regulates muscle specification in adult stem cells by stabilizing PAF1C in chromatin to promote myogenic differentiation. Acts as a transcriptional regulator by binding to the GJA1/Cx43 promoter and enhancing its up-regulation by ESR1/ER-alpha.
Subunit / interactions. Component of the 17S U2 SnRNP complex, a ribonucleoprotein complex that contains small nuclear RNA (snRNA) U2 and a number of specific proteins. Part of the SF3B subcomplex of the 17S U2 SnRNP complex. SF3B associates with the splicing subcomplex SF3A and a 12S RNA unit to form the U2 small nuclear ribonucleoproteins complex (U2 snRNP). Within the SF3B complex interacts directly with SF3B1 and SF3B3. Component of the minor spliceosome, which splices U12-type introns. Within this complex, interacts with CRIPT. Interacts (via N-terminus) with U2AF1 and SRSF5; acts to bridge the two. Interacts (via C-terminus) with EP400 and DDX1; acts to bridge the two. Interacts with the PAF1 complex (PAF1C) composed of CDC73, PAF1, LEO1, CTR9, RTF1 and SKIC8. Within the PAF1C interacts directly with CDC73 and SKIC8. Interacts with RNA polymerase II.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 72 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.
