title: N-terminal sequence homologies in interstitial retinol-binding proteins from 10 vertebrate species.
abstract: We report here the first comprehensive comparative NH2-terminal sequence studies of interstitial retinol-binding protein (IRBPs) from nine mammals (including cattle) and one amphibian. This study has revealed that in many species the N-terminus of IRBP includes a 3-6 amino acid extension. IRBP possessing this leader sequence is sometimes mixed with IRBP from which this sequence has been excised.
