Maguchi et al. (1995) isolated a cDNA encoding calponin-3 (CNN3) by screening a human kidney cDNA library with a rat Cnn3 cDNA. The 329-amino acid CNN3 has a predicted pI of 5.64; it contains a markedly acidic C terminus with a predicted pI of 3.51. The N termini of CNN3 and CNN1 (600806) are highly homologous and basic. CNN3 contains a motif that is tandemly repeated 3 times and is similar to the repeated motif present in CNN1 and CNN2 (602373). Northern blot analysis of human RNAs showed that CNN3 is expressed in both smooth muscle and nonmuscle tissues. Maguchi et al. (1995) suggested that CNN3 is associated with the cytoskeleton but is not involved in contraction.
By FISH analysis, Maguchi et al. (1995) mapped the CNN3 gene to chromosome 1p22-p21.
