Human cyclin-dependent kinase-like proteins and methods of using the same

摘要

Substantially pure human cyclin-dependent kinase-like proteins PITALRE and PISSLRE and isolated protein complexes that comprise PITALRE or PISSLRE are disclosed. Isolated nucleic acid molecule that encode PITALRE or PISSLRE, or a fragment thereof; recombinant expression vectors that comprise nucleic acid sequences that encode PITALRE or PISSLRE; and host cells that comprise such recombinant expression vectors are disclosed. Oligonucleotide molecules that consist of a nucleotide sequence complementary to a portion of the nucleotide sequence that encodes PITALRE or PISSLRE are disclosed. Antibodies which bind to epitopes on PITALRE or PISSLRE are disclosed. Nucleic acid molecules that comprise a nucleotide sequence that encodes phosphorylation deficient PITALRE or a phosphorylation deficient PISSLRE; recombinant vectors and pharmaceutical compositions that comprise such nucleotide sequences are also disclosed. Methods of identifying compounds which inhibit PITALRE activity are disclosed.
