| Description: | Data Source: Sanford-Burnham Center for Chemical Genomics (SBCCG) Source Affiliation: Sanford-Burnham Medical Research Institute (SBMRI, San Diego, CA) Network: NIH Molecular Libraries Production Centers Network(MLPCN) Grant Number: R03 MH094198-01 Assay Provider: Kalle Gehring, Ph.D., McGill University The poly(A) tail of mRNA is bound by several molecules of the poly(A)-binding protein (PABP), an abundant cytoplasmic protein in eukaryotes that promotes translation (2). PABPC1 is a multi-domain protein that contains four phylogenetically conserved RNA recognition motifs (RRM1-4) (3,4) a proline-rich unstructured region and a 70-residue C-terminal domain termed Mlle or PABC (5). Mlle (Mademoiselle) refers to the conserved KITGMLLE signature motif of this domain. The Mlle domain binds proteins with a 12-15 amino acid motif termed PAM2 to regulate PABPC1 involvement in mRNA decay. The goal of this grant is to screen for small molecule modulators of Mlle interactions as chemical probes |
