Functional and structural role of arginine 103 in human erythropoietin.
The identification of amino acid residues essential for function of the hematopoietic growth factor erythropoietin has been approached by several methods, including comparisons of related sequences, immunochemical approaches, mutagenesis, and computer modeling. We have reported previously that mutations within amino acids 100-109 of erythropoietin can have profound effects on the hormone's stru...
متن کاملStructural characterization of human Uch37.
Uch37 is a de-ubiquitylating enzyme that is functionally linked with the 26S proteasome via Rpn13, and is essential for metazoan development. Here, we report the X-ray crystal structure of full-length human Uch37 at 2.95 Å resolution. Uch37's catalytic domain is similar to those of all UCH enzymes characterized to date. The C-terminal extension is elongated, predominantly helical and contains c...
متن کاملHuman erythropoietin receptor: cloning, expression, and biologic characterization.
We have isolated the human homologue of the murine erythropoietin receptor (mEPO-R) from an erythroleukemia line, OCIM1, and from fetal liver. Both the cDNA and protein sequence of the human receptor were 82% homologous to the mEPO-R. Heterologous expression of the human cDNA in COS cells yielded a protein of about 66 Kd. The protein could be specifically immunoprecipitated with either an antib...
متن کاملStructural characterization of human liver heparan sulfate.
The isolation, purification and structural characterization of human liver heparan sulfate are described. 1H-NMR spectroscopy demonstrates the purity of this glycosaminoglycan (GAG) and two-dimensional 1H-NMR confirmed that it was heparan sulfate. Enzymatic depolymerization of the isolated heparan sulfate, followed by gradient polyacrylamide gel, confirmed its heparin lyase sensitivity. The con...
