LIM And Senescent Cell Antigen Like Domains Protein 3 (LIMS3)

LIMS3 Contains 1 LIM zinc-binding domain.LIM domains are protein structural domains, composed of two contiguous zinc finger domains, separated by a two-amino acid residue hydrophobic linker. They are named after their initial discovery in the proteins Lin11, Isl-1 & Mec-3. LIM-domain containing proteins have been shown to play roles in cytoskeletal organisation, organ development and oncogenesis.

LIM-domains mediate protein:protein interactions that are critical to cellular processes. LIM domains have highly divergent sequences, apart from certain key residues. The sequence divergence allow a great many different binding sites to be grafted onto the same basic domain. The conserved residues are those involved in zinc binding or the hydrophobic core of the protein.
