Abstract:
:Although most somatic cells cannot proliferate, immature cells proliferate continuously to produce mature cells. Recently, we cloned mouse PSF1 from a hematopoietic stem cell specific cDNA library and reported that PSF1 is indispensable for the proliferation of immature cells. To identify the PSF1-binding protein, we used the yeast two-hybrid system with PSF1 as bait, and identified and cloned SLD5. SLD5 interacted with a central region of PSF1. Tissue distribution of SLD5 was quite similar to that of PSF1. When overexpressed, SLD5 protein was co-localized with PSF1. These data suggest that PSF1 and SLD5 may cooperate in the proliferation of immature cell populations.
