cpn-3 encodes a calponin homolog, most closely related to its paralog CPN-4 in C. elegans; CPN-3 is more similar to the calponin paralogs transgelin (SM22 alpha) or neuronal protein NP25 than to calponin per se.
Predicted to enable actin filament binding activity. Predicted to be involved in actin filament organization. Located in myofibril. Expressed in anal region; body wall musculature; egg-laying apparatus; enteric muscle; and head neurons.
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
