This antibody is designed, produced, and validated as part of a collaboration between Rockland and the National Cancer Institute (NCI) and is suitable for Cancer, Immunology and Nuclear Signaling research. Myeloid leukemia factor-1 (MLF1) Interacting Protein (also known as PBIP1, MLF1IP1, KLIP1 or KSHV latent nuclear antigen interacting protein 1) is a novel polo-like kinase 1 (Plk1) substrate.  Plk1 phosphorylation of MLF1IP induces ubiquitination and degradation of MLF1IP prior to the metaphase/anaphase transition.  Several Plk1-dependent phosphorylation sites have been identified on MLF1IP by mass spectrometry.  Mutations of these sites stabilize MLF1IP and inhibit mitotic progression.  Subsequent in vitro and in vivo MLF1IP phosphorylation and stability assays have revealed that phosphorylation of Thr78 is critical for triggering Plk1-dependent MLF1IP degradation.  Expression of a non-degradable Thr78Ala mutant was sufficient to induce a mitotic block.  Timely phosphorylation of MLF1IP on Thr78 by Plk1 is critical for eliminating the MLF1IP-imposed mitotic block prior to anaphase onset.  MLF1IP is speculated to be a novel tumor suppressor, whose function is required for proper sister-chromatid separation.  Loss of MLF1IP function may result in improper segregation of chromosomes and genomic instability, thus promoting tumorigenesis.

Application Note

This affinity purified antibody has been tested for use in ELISA and western blotting.  Specific conditions for reactivity should be optimized by the end user.  Expect a band approximately 65 kDa in size corresponding to MLF1IP protein by western blotting in the appropriate cell lysate or extract.


This affinity purified antibody is directed against human MLF1IP protein.  The product was affinity purified from monospecific antiserum by immunoaffinity chromatography.  A BLAST analysis was used to suggest cross-reactivity with MLF1IP protein from human, dog, bovine and chimpanzee based on 100% homology with the immunizing sequence.  Expect partial reactivity with homologues from rat and mouse (90% homology).  Reactivity against homologues from other sources is not known.  This antibody reacts with MLF1IP protein that is either phosphorylated or non-phosphorylated at Thr78.
