Presynaptic Membrane (PSMAB) ELISA Kit for Chicken

This gene encodes a member of a family of proteins that possess a 100-amino acid PDZ domain at the N terminus and one to three LIM domains at the C-terminus. This family member functions as a scaffold protein that tethers protein kinases to the Z-disk in striated muscles. It is thought to function in cardiomyocyte expansion and in restraining postsynaptic growth of excitatory synapses. Alternative splicing of this gene results in multiple transcript variants.

LIM: an adaptor protein of the Enigma family. Contains three LIM domains and one PDZ domain. LIM domains are cysteine-rich double zinc fingers composed of 50 to 60 amino acids that are involved in protein-protein interactions. LIM domain-containing proteins are scaffolds for the formation of multiprotein complexes. The proteins are involved in cytoskeleton organization, cell lineage specification, organ development, and oncogenesis. Enigma family proteins possess a 100-amino acid PDZ domain in the N terminus and 1 to 3 LIM domains in the C terminus.
