pubmed:abstractText |
Protein 4.1 is an extrinsic membrane protein that facilitates the interaction of spectrin and actin in the erythroid membrane skeleton and exists as several structurally related polypeptides in chickens. The ratio of protein 4.1 variants is developmentally regulated during terminal differentiation of chicken erythroid and lenticular cells. To examine the mechanisms by which multiple chicken protein 4.1 variants are differentially expressed, we have isolated cDNA clones specific for chicken erythroid protein 4.1. We show that a single protein 4.1 gene gives rise to multiple 6.6-kilobase mRNAs by differential RNA processing. Furthermore, the ratios of protein 4.1 mRNAs change during chicken embryonic erythropoiesis. We observe a quantitative difference in variant ratios when protein 4.1 is synthesized in vivo or in a rabbit reticulocyte lysate in vitro. Our results show that the expression of multiple protein 4.1 polypeptides is regulated at the levels of translation and RNA processing.
