- Abstract
A form of the human erythropoietin receptor (EPOR) was identified in which the cytoplasmic region is truncated by alternative splicing. The truncated form of the receptor (EPOR-T) is the most prevalent form of EPOR in early-stage erythroid progenitor cells, but the full-length EPOR (EPOR-F) becomes the most prevalent form in late-stage progenitors. EPOR-T can transduce a mitogenic signal. However, cells transfected with EPOR-T are more prone to programmed cell death than those expressing EPOR-F. EPOR-F may transduce a signal to prevent programmed cell death that is independent of the mitogenic signal, and alternative splicing of the EPOR gene may have an important role in erythropoiesis.
