Summary: Actins are highly conserved proteins that are involved in various types of cell motility and maintenance of the cytoskeleton. In vertebrates, three main groups of actin isoforms, alpha, beta, and gamma, have been identified. The alpha actins are found in muscle tissues and are a major constituent of the contractile apparatus. The beta and gamma actins co-exist in most cell types as components of the cytoskeleton, and as mediators of internal cell motility. Actin, gamma 1, encoded by this gene, is a cytoplasmic actin found in non-muscle cells. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2015]

Nucleotide- and Protein-Dependent Functions of Actg1.
Title: Nucleotide- and Protein-Dependent Functions of Actg1.
Data, including data from studies using knockout mice, suggest that Actb and Actg1 are enriched in isolated membrane preparations from skeletal muscle which represent interface between mitochondria and sarco-endoplasmic reticulum; these structures appear to be important in signaling, mitochondrial dynamics, and muscle relaxation. (Actb = beta actin cytoplasmic 1; Actg1 = actin gamma cytoplasmic 1)
Title: Impaired muscle relaxation and mitochondrial fission associated with genetic ablation of cytoplasmic actin isoforms.
Two actin isoforms, beta- and gamma-actin, are crucial for slow, rapid, bulk, and overshoot endocytosis at large calyx-type synapses, and for slow endocytosis and bulk endocytosis at small hippocampal synapses.
Title: Actin Is Crucial for All Kinetically Distinguishable Forms of Endocytosis at Synapses.
Splicing to include exon 3a is concomitant with previously described down-regulation of Actg1 in differentiating C2C12 cells
Title: A novel actin mRNA splice variant regulates ACTG1 expression.
Beta- and gamma-cytoplasmic actins are required for meiosis in mouse oocytes.
Title: Beta- and gamma-cytoplasmic actins are required for meiosis in mouse oocytes.
These data support an essential role for beta-actin in regulating cell migration and gene expression through control of the cellular G-actin pool
Title: β-Actin specifically controls cell growth, migration, and the G-actin pool.
Results demonstrate overlapping developmental roles but unique post-developmental functions for beta-actin and gamma-actin in maintaining hair cell stereocilia.
Title: β-actin and γ-actin are each dispensable for auditory hair cell development but required for Stereocilia maintenance.
Since the total amount of actin protein was maintained in Actg1(-/-) cells, our data suggests a distinct requirement for gamma(cyto)-actin in cell growth and survival.
Title: Delayed embryonic development and impaired cell growth and survival in Actg1 null mice.
arginylated gamma-actin, unlike beta-, was highly unstable and selectively ubiquitinated and degraded in vivo; instability was regulated by differences in nucleotide coding sequence between the actin isoforms, which conferred different translation rates
Title: Differential arginylation of actin isoforms is regulated by coding sequence-dependent degradation.
Eplin-alpha transcription is regulated by actin-MAL-SRF signalling.
Title: Epithelial Protein Lost in Neoplasm alpha (Eplin-alpha) is transcriptionally regulated by G-actin and MAL/MRTF coactivators.

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.
