Previous GeneCards Identifiers for ARPC1B Gene
This gene encodes one of seven subunits of the human Arp2/3 protein complex. This subunit is a member of the SOP2 family of proteins and is most similar to the protein encoded by gene ARPC1A. The similarity between these two proteins suggests that they both may function as p41 subunit of the human Arp2/3 complex that has been implicated in the control of actin polymerization in cells. It is possible that the p41 subunit is involved in assembling and maintaining the structure of the Arp2/3 complex. Multiple versions of the p41 subunit may adapt the functions of the complex to different cell types or developmental stages. This protein also has a role in centrosomal homeostasis by being an activator and substrate of the Aurora A kinase. [provided by RefSeq, Mar 2011]
GeneCards Summary for ARPC1B Gene
ARPC1B (Actin Related Protein 2/3 Complex Subunit 1B) is a Protein Coding gene. Among its related pathways are Bacterial invasion of epithelial cells and Regulation of actin dynamics for phagocytic cup formation. GO annotations related to this gene include actin binding and structural constituent of cytoskeleton. An important paralog of this gene is ARPC1A.
UniProtKB/Swiss-Prot for ARPC1B Gene
Functions as component of the Arp2/3 complex which is involved in regulation of actin polymerization and together with an activating nucleation-promoting factor (NPF) mediates the formation of branched actin networks.
