Calponin-2 (IPR029974)

Short name: CNN2

Overlapping homologous superfamilies

Family relationships


Calponin-2 (CNN2) belongs to the calponin family, whose members have a N-terminal calponin homology domain (CH) and a C-terminal calponin-like repeat.

Calponin is an actin filament binding protein and an myosin ATPase inhibitor expressed in smooth muscle and non-muscle cells [PMID: 18946636]. The structure of the CH domain has been solved [PMID: 18477568]. In vertebrates three calponin isoforms have been found [PMID: 18304026].
