Anti-syntaxin1B antibodies enable researchers to detect and measure the syntaxin1B antigen in biological samples. This target is a reported synonym of the STX1B gene, which encodes syntaxin 1B. This protein is known to function in intracellular protein transport and the regulation of gene expression, among other biological roles. The human version of syntaxin1B has a canonical amino acid length of 288 residues and a protein mass of 33.2 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in the hippocampus, cerebral cortex, cerebellum, and caudate. syntaxin1B is a member of the Syntaxin protein family.
