SRRM1 encodes the human gene, Serine/arginine repetitive matrix 1. It may also be known as: Serine/arginine repetitive matrix protein 1; SRm160; Ser/Arg-related nuclear matrix protein; SR-related nuclear matrix protein of 160 kDa; plenty of prolines 101-like; 160-KD; POP101. The encoded protein has an amino acid length of 904 and a mass of 102.3 kDa. SRRM1 is a member of the Splicing factor SR family. Homologs of this gene exist in other organisms, including: Fly, Frog.
