title: Several splicing variants of isl-1 like genes in the chinook salmon (Oncorhynchus tschawytscha) encode truncated transcription factors containing a complete LIM domain.
abstract: Several novel cDNA clones have been isolated from a chinook salmon pituitary cDNA library. Sequence analysis of these clones indicates that they are closely related to the rat LIM domain homeobox gene, isl-1. Due to differential splicing, several of the clones encode truncated polypeptides containing a complete copy of the LIM domain without the homeodomain and C-terminal activation domain. The roles of these truncated polypeptides are discussed.
