Vascular endothelial cells (VEC) transduce mitogenic and chemoattractant signals in response to erythropoietin (Epo). An analysis of changes in gene expression in VEC would be helpful to understanding the molecular nature of mitogenic signals. An effective method for analysis of gene expression is through differential display. Using this approach, we obtained from Epo-treated human microvascular endothelial cells (HMVEC) a cDNA fragment with characteristics of the 3'end of mRNA. Using the cDNA fragment, we then isolated a full-length clone from a HMVEC cDNA library. The cDNA of interest encodes a protein consisting of 404 amino acids with a carboxy-terminal end sequence identical to glialblastoma cell differentiation factor-related protein (GBDR1). Northern blot analysis showed that GBDR1 mRNA was ubiquitously expressed in human tissues. In Southern blot analysis, GBDR1 cDNA identified a single gene on chromosome 9. Since analysis of the amino acid sequence revealed several putative phosphorylation sites for different protein kinases, the GBDR1 protein was expressed and purified from bacterial extracts and, as predicted, casein kinase II phosphorylated GBDR1 in vitro. Immunofluorescence and biochemical data revealed that the GBDR1 protein is not entirely localized in the cytosolic fraction, suggesting that it may interact with another protein(s). These findings demonstrate that GBDR1 is an intracellular signaling molecule that may play a role in the regulation of endothelial cell growth.
