| Type: | Family | Name: | Smooth muscle protein/calponin |
| Description: | Calponin is a smooth muscle-specific, actin-, tropomyosin- and calmodulin-binding protein believed to be involved in regulation or modulation of contraction []; interaction of the protein with actin inhibits actomyosinMgATPase activity. Multiple isoforms are found in smooth muscle []. Calponin is a basic protein of ~34 Kd []. The protein contains three repeats of awell-conserved 26-residue domain (see ). | Short Name: | SM22_calponin |
