SUGP1 encodes the human gene, SURP and G-patch domain containing 1. It may also be known as: SURP and G-patch domain-containing protein 1; Splicing factor 4; RNA-binding protein RBP; F23858; SF4; SURP and G patch domain containing 1. The encoded protein has an amino acid length of 645 and a mass of 72.5 kDa. Other isoforms may exist. Homologs of this gene exist in other organisms, including: Mouse, Rat, Zebrafish, Chicken.
