Summary: Enables actin filament binding activity. Acts upstream of or within actin filament bundle assembly. Located in several cellular components, including actin filament; phagocytic cup; and ruffle. Is expressed in several structures, including brain; cardiovascular system; female reproductive system; gut; and yolk sac. Human ortholog(s) of this gene implicated in nicotine dependence. Orthologous to human LCP1 (lymphocyte cytosolic protein 1). [provided by Alliance of Genome Resources, Jul 2025]

Among the proteins found to preferentially bind clasped rather than the isolated alphaM and beta2 subunits was L-plastin (LCP1, also known as plastin-2), which binds to and maintains the inactive state of alphaMbeta2 integrin in vivo and thereby regulates leukocyte adhesion to integrin ligands under flow.
Title: LCP1 preferentially binds clasped αMβ2 integrin and attenuates leukocyte adhesion under flow.
Our data suggest that targeted disruption of L-plastin increases trabecular bone volume, and phosphorylation of Ser5 in L-plastin in the Lrrk1 signaling pathway may in part contribute to actin assembly in mature osteoclasts.
Title: LRRK1 regulation of actin assembly in osteoclasts involves serine 5 phosphorylation of L-plastin.
It is shown that TNF-alpha signaling regulates the phosphorylation of serine-5 and -7 in L-plastin which increases the actin bundling capacity of L-plastin and hence the formation of nascent sealing zones in mouse osteoclasts.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
