Anti-SPIN2B antibodies are used in the immunodetection of the protein spindlin family member 2B. In humans, the canonical protein has a reported length of 258 amino acid residues and a mass of 29.2 kDa. Its subcellular localization is in the nucleus. It is notably expressed in all the examined tissues with highest expression in the liver, followed by heart, stomach, kidney, skeletal muscle, placenta, and pancreas. A member of the SPIN/STSY protein family, SPIN2B is reported to be involved in regulation of cell cycle progression, this activity is related to the inhibition of apoptosis following the removal of essential growth factors. Synonyms for this target antigen include spindlin family, member 2 duplicate, spindlin-like protein 2B, telomeric SPIN2 copy, and spindlin-2B. SPIN2B gene orthologs have been reported in the mouse and rat species. ELISA, Western Blot, and Immunohistochemistry are common applications for SPIN2B antibodies.
