这个基因编码人类Arp2/3蛋白复合物的七个亚单位之一Arp2/3蛋白复合物参与了细胞内肌动蛋白聚合的调控，并在进化过程中得以保存由这个基因p34亚单位编码的蛋白质的确切作用尚未确定迄今为止，已经对两种可选的拼接变体进行了表征。已经描述了其他可选的拼接变体，但尚未确定其全长性质。[由RefSeq提供，2008年7月]
This gene encodes one of seven subunits of the human Arp2/3 protein complex. The Arp2/3 protein complex has been implicated in the control of actin polymerization in cells and has been conserved through evolution. The exact role of the protein encoded by this gene, the p34 subunit, has yet to be determined. Two alternatively spliced variants have been characterized to date. Additional alternatively spliced variants have been described but their full length nature has not been determined. [provided by RefSeq, Jul 2008]
