Pim-1 Oncogene (PIM1)

Proto-oncogene serine/threonine-protein kinase Pim-1 is an enzyme encoded by the PIM1 gene. The protooncogene PIM1 encodes a protein kinase upregulated in prostate cancer (Dhanasekaran et al., 2001).Viral leukemogenesis in mice is often initiated by proviral activation of the highly conserved cellular gene Pim1. Domen et al. (1987) compared the nucleotide sequence of human and mouse PIM1 cDNAs. Meeker et al. (1987) also characterized the human PIM1 gene. The deduced amino acid sequence showed significant homology to a number of the protein kinases but did not have a transmembrane region. Studies of expression of this gene using Northern blots of human cell lines showed it to be transcribed primarily in B-lymphoid and myeloid cell lines.
