ACTG1 Research Reagents

Actin, cytoplasmic 2 is a protein in humans that is encoded by ACTG1 gene. Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.

ACTG1 Background

The ACTG1 gene encodes the cytoskeletal protein gamma-actin, which plays an important role in determining cell shape and controlling cell movement. Gamma-actin protein also refers to as ACTG1. Human gamma-actin is 41.8 kDa in molecular weight and 375 amino acids in length. Gamma-actin is widely expressed in cellular cytoskeletons of many tissues, particularly abundant in the auditory hair cells of the cochlea [1]. The hair cells are essential for normal hearing. Mutations in ACTG1 are associated with DFNA20/26, a subtype of autosomal dominant non-syndromic sensorineural progressive hearing loss [1][2][6]. And Baraitser-Winter syndrome is also linked to ACTG1 mutations [3]. Studies have identified ACTG1 with significantly high expression in skin cancer tissue and suggested that ACTG1 can regulate cell proliferation and migration through the ROCK signaling pathway [4]. And other studies have shown that ACTG1 recurrent mutation leads to isolated ocular coloboma (OC), a defect in optic fissure closure that is a common cause of severe congenital visual impairment [5]. Kevin J. Sonnemann et al. observed that skeletal muscle-specific cytoplasmic γ-Actin knockout (Actg1-msKO) mice dysfunctioned in whole-body tension and isometric twitch force, although their muscle development proceeded normally. They concluded that cytoplasmic γ-Actin is not required for skeletal muscle development but its absence leads to a progressive myopathy [7].
