Mouse SEZ6L Antibody

SEZ6L (Seizure 6-Like protein; also BSRP-B/Brain-specific receptor-like protein B) is a 200-210 kDa member of the SEZ6 family of proteins. It is expressed in the plasma membrane and ER of CNS neurons, particularly cerebellar interneurons plus Purkinje and granule cells. SEZ6L likely regulates Ca++ availability and thus impacts PKC alpha activation and mGluR1 signaling. Mature mouse SEZ6L is a 932 amino acid (aa) type I transmembrane protein. It contains an 866 aa extracellular domain (ECD) (aa 32-897) and a 45 aa cytoplasmic tail. The ECD shows three CUB domains and five short consensus repeats (SCRs). There is one 190-200 kDa splice variant termed BSRP-B that contains a Phe substitution for aa 807-872 of the fifth SCR domain. Over aa 32-889, mouse SEZ6L shares 80% and 97% aa identity with human and rat SEZ6L, respectively.
