SRRM4 encodes the human gene, Serine/arginine repetitive matrix 4. It may also be known as: Serine/arginine repetitive matrix protein 4; Neural-specific serine/arginine repetitive splicing factor of 100 kDa; Neural-specific SR-related protein of 100 kDa; nSR100; Medulloblastoma antigen MU-MB-2.76; KIAA1853; MU-MB-2.76. The encoded protein has an amino acid length of 611 and a mass of 68.6 kDa. Other isoforms may exist. SRRM4 is a member of the NSR100 family. Homologs of this gene exist in other organisms, including: Mouse, Zebrafish, Frog, Chicken.
