Transcription activator that binds calmodulin in a calcium-dependent manner in vitro (PubMed:12218065). Binds to the DNA consensus sequence 5'-[ACG]CGCG[GTC]-3' (By similarity). Regulates transcriptional activity in response to calcium signals (Probable). Expressed in roots, stems, leaves, sepals, petals, stamen filaments, top of carpels, anthers and siliques, but not in stigmas. By heat shock, UVB, salt, wounding, abscisic acid, H(2)O(2) and salicylic acid. Incomplete sequence. Belongs to the CAMTA family. Truncated N-terminus.
