PIM1 is a proto-oncogene that belongs to a family of serine/threonine protein kinases that are highly conserved through evolution in multicellular organisms. Originally identified from Moloney murine leukemia virus induced T-cell lymphomas in mice, PIM1 is involved in the control of cytokine-mediated cell proliferation, differentiation and survival of lymphoid and myeloid cells as well as others. Expression of PIM1 can be stimulated by a variety of growth factors and is regulated at four different levels: transcriptional, post-transcriptional, translational and post-translational. Expression of PIM1 is mediated through activation of the JAK/STAT pathway.

The human pim-1 proto-oncogene was expressed in Escherichia coli as a glutathione-S-transferase (GST)-fusion protein and the enzymatic properties of its kinase activity were characterized. Likewise, a Pim-1 mutant lacking intrinsic kinase activity was constructed by site-directed mutagenesis (Lys67 to Met)

The mouse PIM-1 gene has been implicated in the evolution of retrovirus-associated mouse lymphomas. We have initiated a study of the human PIM-1 gene because of its potential importance as a human oncogene. We have isolated genomic and cDNA clones
