PIN is an alias for the gene, Dynein, light chain, LC8-type 1, in humans. Other names include: Dynein light chain 1, cytoplasmic; 8 kDa dynein light chain; DLC8; Dynein light chain LC8-type 1; Protein inhibitor of neuronal nitric oxide synthase; DNCL1; DNCLC1; LC8; LC8a. The encoded protein has an amino acid length of 89 and a mass of 10.4 kDa. Other isoforms may exist. PIN is a member of the Dynein light chain family. This gene shares homology with other species, including: Mouse, Rat, Frog, Fly.
