Anti-C15orf59 antibodies enable researchers to detect and measure the C15orf59 antigen in biological samples. This target is a reported synonym of the INSYN1 gene, which encodes inhibitory synaptic factor 1. This protein is a known component of the protein machinery at the inhibitory synapses, probably acting as a scaffold. The human version of C15orf59 has a canonical amino acid length of 293 residues and a protein mass of 31.9 kilodaltons. It is reported to be notably expressed in the heart muscle, colon, and cerebral cortex. C15orf59 is a member of the INSYN1 protein family.
