Anti-BRIT1 antibodies enable researchers to detect and measure the BRIT1 antigen in biological samples. This target is a reported synonym of the MCPH1 gene, which encodes microcephalin 1. This protein is known to function in bone development and nervous system development, among other biological roles. The human version of BRIT1 has a canonical amino acid length of 835 residues and a protein mass of 92.8 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types.
