Pnisr is a symbol for the gene, PNN-interacting serine/arginine-rich protein, in humans. Other names include: Arginine/serine-rich protein PNISR; SR-related protein; SR-rich protein; Serine/arginine-rich-splicing regulatory protein 130; SRrp130; Splicing factor, arginine/serine-rich 130; Splicing factor, arginine/serine-rich 18; C6orf111; HSPC306; SFRS18; bA98I9.2. The encoded protein has an amino acid length of 805 and a mass of 92.6 kDa. Other isoforms may exist. Pnisr is a member of the Splicing factor SR family. This gene shares homology with other species, including: Mouse, Rat, Zebrafish, Frog.
