Anti-PDLIM4 Antibody Picoband®

PDZ and LIM domain protein 4 is a protein that in humans is encoded by the PDLIM4 gene. RIL, also known as PDLIM4 is a putative tumor suppressor gene. RIL is transcriptionally repressed by hypermethylation in a variety of tumors including breast and prostate. The difference in methylation status of RIL between normal and cancerous tissues is being investigated as to determine the use of RIL as a potential biomarker. Two isoforms of human RIL one have been identified.

E.coli-derived human PDLIM4 recombinant protein (Position: Y137-D271) . Human PDLIM4 shares 91.2% and 89% amino acid (aa) sequence identity with mouse and rat PDLIM4, respectively.
