Pdlim4 Gene Summary [Rat]
Enables alpha-actinin binding activity. Involved in several processes, including excitatory chemical synaptic transmission; positive regulation of stress fiber assembly; and regulation of postsynaptic membrane neurotransmitter receptor levels. Located in several cellular components, including endosome lumen; postsynaptic membrane; and stress fiber. Is active in glutamatergic synapse and postsynaptic density. Human ortholog(s) of this gene implicated in osteoporosis. Orthologous to human PDLIM4 (PDZ and LIM domain 4). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Pdlim4 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
