Calmodulin 1 is a protein that in humans is encoded by the CALM1 gene.[1]



Calmodulin 1 is the archetype of the family of calcium-modulated (calmodulin) proteins of which nearly 20 members have been found. They are identified by their occurrence in the cytosol or on membranes facing the cytosol and by a high affinity for calcium. Calmodulin contains 148 amino acids and has 4 calcium-binding motifs. Its functions include roles in growth and the cell cycle as well as in signal transduction and the synthesis and release of neurotransmitters.[2]


Calmodulin 1 has been shown to interact with AKAP9,[3] TRPV1,[4] Androgen receptor,[5] IQGAP1[6][7] and PPEF1.[8]
