A chick skeletal-muscle alpha-actinin gene gives rise to two alternatively spliced isoforms which differ in the EF-hand Ca(2+)-binding domain.

Abstract excerpt

A chick non-muscle alpha-actinin cDNA probe encoding the EF-hand region of molecule was used to screen a lambda gt10 chick brain cDNA library from 14-day embryos. A partial 2.1-kb alpha-actinin cDNA was isolated (8W cDNA) which encoded a protein identical to chick skeletal-muscle alpha-actinin, except in the C-terminal part of the first EF hand. In the variant, the 22 residues found in the skeletal-muscle isoform...
