Anti-SK1 antibodies enable researchers to detect and measure the SK1 antigen in biological samples. This target is a reported synonym of the KCNN1 gene, which encodes potassium calcium-activated channel subfamily N member 1. This protein is known to function in chemical synaptic transmission and potassium ion transport, among other biological roles. The human version of SK1 has a canonical amino acid length of 543 residues and a protein mass of 60 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the membrane of cells. SK1 is a member of the Potassium channel KCNN protein family.
