p23-like NUD (nuclear distribution) C-like domain of mammalian(m) NUDC and similar proteins. Mammalian(m) NUDC associates both with the dynein complex and also with an anti-inflammatory enzyme, platelet activating factor acetylhydrolase I, PAF-AH(I) complex, through binding mNUDF, the regulatory beta subunit of PAF-AH(I). mNUDC is important for cell proliferation both in normal and tumor tissues. Its expression is elevated in various cell types undergoing mitosis or stimulated to proliferate, with high expression levels observed in leukemic cells and tumors. For a leukemic cell line, human NUDC was shown to activate the thrombopoietin (TPO) receptor (Mpl) by binding to its extracellular domain, and promoting cell proliferation and differentiation.
