Abstract
PHR protein family consists of C. elegan Rpm-1/Drosophila Highwire/Zebrafish Esrom/Mouse Phr-1/Human Pam. Esrom is required for correct neurites exiting the paused state at intermediate targets as well as pteridine synthesis. This study reports the identification and characterization of two novel Esrom splice variants, named splice variants 2 (splicing out 5' 24 bp of exon 17) and 3 (splicing out 5' 24 bp of exons 17 and 18). Polypeptides encoded by 5' 24 bp of exons 17 and 18 are part of basic amino-acid-rich region inside Esrom RCC1-like domain (RLD). These two splice variants maintain the whole protein reading frame and alternative exons usage patterns are conserved with mammal. At different developmental stages and adult zebrafish tissues, abundances of these splice variants are different. Importantly, by yeast two-hybrid screen and confocal colocalization analysis, it was found that alternative splicing of exon 18 regulates Esrom RLD interaction with kinesin family member 22 and G protein beta-subunit 1. Taken together, these results suggest that Esrom RLD functions are regulated by alternative splicing at temporal and spatial-specific manner.
