Recombinant Human PHD Finger Protein 5A

Source : Escherichia Coli. PHF5A Human Recombinant produced in E. coli is a single polypeptide chain containing 133 amino acids (1-110) and having a molecular mass of 14.8kDa. PHF5A is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. PHD Finger Protein 5A, also known as PHF5A, is a part of the PHD-finger superfamily and acts as a chromatin-associated protein. PHF5A is a subunit of the splicing factor 3b protein complex which along 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 way and anchors the U2 snRNP to the pre-mRNA. PHF5A holds a PHD-finger-like domain which is flanked by highly basic N- and C-termini.
