ab32787 gave a positive result in rat and mouse brain tissue lysates. CAPS1 is known not to be expressed in heart (Speidel et al, J. Biol. Chem., Vol. 278, Issue 52, 52802-52809. PMID: 14530279). Mouse heart tissue lysate can be used as a negative control for ab32787.

CAPS1 (Ca2+-dependent activator protein for secretion) belongs to the CAPS/Cadps family which consists of two members, CAPS1 and CAPS2. The CAPS family proteins are involved in the secretion of different secretory substances in developing and postnatal brains. In addition CAPS1 regulates catecholamine release from neuroendocrine cells and is expressed predominantly in the brain.
