PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	one LIM zinc-binding domain
	one PDZ/DHR domain
	a ZASP-like motif, between PDZ and LIM domains, required for the interaction of PDLIM3 internal region with the alpha-actinin rod and for targeting to the Z-line

HOMOLOGY

interspecies	ortholog to rattus pdlim3
	ortholog to murine Pdlim3

Homologene

FAMILY

ALP subfamily of PDZ-LIM proteins

CATEGORY

adaptor

SUBCELLULAR LOCALIZATION	intracellular
	intracellular,cytoplasm,cytoskeleton

basic FUNCTION	may be acting as an adapter that brings other proteins to the cytoskeleton
	critical role on muscle differentiation, likely via cytoskeletal regulation of SRF

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

a component

INTERACTION

DNA

RNA

small molecule	metal binding,
	Zn2+

protein

binds ACTN2 in the Z-discs of muscle, and the ZASP-like motif is needed for this interaction
