Actin-like protein 6A is a protein that in humans is encoded by the ACTL6A gene.[3][4][5]

Function[edit]

This gene encodes a family member of actin-related proteins (ARPs), which share significant amino acid sequence identity to conventional actins. Both actins and ARPs have an actin fold, which is an ATP-binding cleft, as a common feature. The ARPs are involved in diverse cellular processes, including vesicular transport, spindle orientation, nuclear migration and chromatin remodeling. This gene encodes a 53 kDa subunit protein of the BAF (BRG1/brm-associated factor) complex in mammals, which is functionally related to SWI/SNF complex in S. cerevisiae and Drosophila; the latter is thought to facilitate transcriptional activation of specific genes by antagonizing chromatin-mediated transcriptional repression. Together with beta-actin, it is required for maximal ATPase activity of BRG1, and for the association of the BAF complex with chromatin/matrix. Three transcript variants that encode two different protein isoforms have been described.[5]

Interactions[edit]

ACTL6A has been shown to interact with SMARCA2,[6][7][8] Myc,[7] Transformation/transcription domain-associated protein,[7] RuvB-like 1[7] and SMARCA4.[3][6]
