英文摘要HSPC144 is a newly identified gene in human CD34(+) hematopoietic stem/progenitor cells, In this work. we have expressed and purified the 225-residue protein from Escherichia coli BL21 (DE3) and identified a stable fragment HSPC144-P (residues 44 225) by limited proteolysis method. The HSPC144-P fragment exhibits high stability with a little increase of secondary structure percentage as compared with the full-length protein. We anticipated that the N-terminally truncated protein possesses a more compact structure. By sequence analysis, the proteolytic fragment shares a great similarity with DUF5899 domain. I previously identified domain with unknown function. This novel domain is highly conserved in Thy28 proteins and is worthy of structural and functional studies. We have subcloned this homologous domain from HSPC144 protein and purified to homogeneity for structure analysis. The N-15 and N-15/C-13-labeled DUF589 domain samples have been prepared successfully and determination of the NMR structure is in progress. (c) 2005 Elsevier Inc. All rights reserved.
