By searching an EST database for actin-related proteins, Harata et al. (2001) identified ARPM1. The deduced 372-amino acid protein contains an actin-like ATP/ADP-binding pocket and 2 nuclear export signals. However, residues likely to be involved in actin-actin and actin-myosin (see 160730) contacts are not well conserved in ARPM1. ARPM1 shares 50% amino acid identity with beta-actin (102630) and 46% identity with ARPM2 (608535). RT-PCR detected ARPM1 expression in all tissues tested; the level of expression was lower than that of beta-actin.
Harata et al. (2001) mapped the ARPM1 gene in silico to chromosome 3q26.2.
