Summary: Predicted to enable ATP binding activity and hydrolase activity. Involved in skeletal muscle fiber development. Predicted to be located in several cellular components, including filopodium; lamellipodium; and sarcomere. Predicted to be part of protein-containing complex. Predicted to be active in actin filament; stress fiber; and striated muscle thin filament. Is expressed in several structures, including alimentary system; brain; genitourinary system; heart; and limb. Used to study nemaline myopathy 3. Human ortholog(s) of this gene implicated in congenital myopathy 2B; congenital myopathy 2C; and nemaline myopathy 3. Orthologous to human ACTA1 (actin alpha 1, skeletal muscle).

alpha smooth muscle actin (alphaSMA) was identified as a marker of osteoprogenitor cells in bone and periodontium.

Data indicate roles for linkers of nucleus to cytoskeleton (LINC) molecules nesprin2giant and nesprin3, which anchor actin cap fibers to the nucleus.
Title: The LINC-anchored actin cap connects the extracellular milieu to the nucleus for ultrafast mechanotransduction.
Asp286Gly acts as a "poison-protein" and according to the computational analysis it modifies the actin-actin interface. This phenomenon is likely to prevent proper myosin cross-bridge binding.
Title: Nemaline myopathy-related skeletal muscle α-actin (ACTA1) mutation, Asp286Gly, prevents proper strong myosin binding and triggers muscle weakness.
Data show that upon actin binding, the two domains of utrophin become dramatically separated and ordered, indicating a transition to a single open and extended conformation.

Data indicated that CacyBP/SIP could simultaneously interact with tubulin and actin, suggesting that CacyBP/SIP might link actin and tubulin cytoskeletons.
Title: Tubulin binding protein, CacyBP/SIP, induces actin polymerization and may link actin and tubulin cytoskeletons.
Results provide the genetic proof that platelet production from megakaryocytes strictly requires dynamic changes in the actin cytoskeleton.

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.
