Who's who among the Saccharomyces cerevisiae actin-related proteins? A classification and nomenclature proposal for a large family

Yeast. 1997 Sep 15;13(11):1053-8. doi: 10.1002/(SICI)1097-0061(19970915)13:11<1053::AID-YEA164>3.0.CO;2-4.

Abstract

Inspection of the complete Saccharomyces cerevisiae genome sequence and analysis of the actin-related proteins (ARPs) found therein revealed seven proteins, in addition to the previously designated actin-related proteins Arp1, Arp2 and Arp3, which contained substantial blocks of conservation relative to a chosen sub-set of actins. We have ordered the new ARPs relative to this group of actins and propose to name the more distantly related ARP members, according to their amino acid identity and similarity, Arp4-Arp10. Most of these proteins appear to represent the first example of new classes of ARPs, each of which may have specific localization(s) and cellular function(s). Recently reported ARPs from other species have also been included in the phylogenetic tree derived from the overall alignment of 29 actins and 28 ARPs.
