Gene Information

human ... CAPZB(832)

General description

The gene CAPZB (F-actin-capping protein subunit β) is mapped to human chromosome 1p36.1. The protein co-localizes with the actin filaments.


synthetic peptide corresponding to amino acids 71-85 of human CAPZB


Anti-CAPZB (71-85) antibody produced in rabbit is suitable for western blot at a dilution of 1:500-1:2,000.

Biochem/physiol Actions

CAPZB (F-actin-capping protein subunit β) are F-actin-capping proteins. Absence of CAPZB reduces actin filament depolymerization and capping. CAPZB also plays a role in the regulation of cell morphology. T cell surface protein CD2 regulates T cell signalling partly by associating with CAPZB, CD2AP (CD2-associated protein) and CIN85 (SH3 domain-containing kinase-binding protein 1).

Physical form

The role of ion channels in carcinogenesis and tumor progression remains unclear. We have used suppression subtractive hybridization of mRNA from paired normal colon epithelium and tumor, followed by quantitative kinetic RT-PCR, to demonstrate that the transcription of two members...

Recruitment of CD2 to the immunological synapse in response to antigen is dependent on its proline-rich cytoplasmic tail. A peptide from this region (CD2:322-339) isolated CMS (human CD2AP); a related protein, CIN85; and the actin capping protein, CAPZ from a...
