Calponins

A family of actin binding proteins mostly in smooth muscle. Calponins include most abundant alpha-calponin (h1 or basic); beta-calponin; neutral calponin (h2 calponin); acidic calponin, SM22, and transgelin. Calponin family members have N-terminal single Calponin Homology (CH) domain and multiple C-terminus 23-amino acids long calponin-like repeats called CLICK-23. Calponins participate in modulation of smooth muscle contraction by binding to ACTINS (F- and G-Actins), CALMODULIN and TROPOMYSIN.
