CIB2 Background

The Calmyrin2 (CaMy2, Cib2) is a novel calcium-binding protein with EF-hand found recently in skeletal muscle. Calcium signals are transmitted by Ca²⁺ binding proteins, which own the same myristoylated N-terminus. CaMy2 is myristoylated in vivo, similarly as CaMy1 and VILIP1, which in response to Ca-signal exhibit redistribution from the cytoplasm to membranes by so called Ca/myristoyl switch. CaMy2 was detected mainly in subcellular membranes and no Ca-dependent translocation was observed. In summary, although CaMy2 and CaMy1 undergo myristoylation in vivo, they do not exhibit Ca/myristoyl switch, but instead seem constitutively associated with subcellular membranes. In addition, observed differences in subcellular localisation of the two members of CaMy protein family suggest they are specialized to transmit Ca transients at their specific membrane locations mediating different Ca-signaling pathways.
