Sexual networking analysis revealed a ten-person cluster with higher VLs at diagnosis (90% with VLs > 100,000 copies/mL vs. 33%, p=0.015). Phylogenetic analysis of pol sequences showed a cluster of 14 cases with sequences that shared 98-100% HIV-1 nucleotide identity. This investigation of newly infected HIV-1 cases in Vermont led to identification of a cluster that appeared more likely to have advanced HIV-1 disease and neurosyphilis. Identification of a cluster was strongly supported by both phylogenetic and network analyses of HIV-1 pol sequences.

To provide insights into the assembly and regulation of this protein family, we focused on a subcomplex of the Saccharomyces cerevisiae RSC comprising its ATPase (Sth1), the essential actin-related proteins (ARPs) Arp7 and Arp9 and the ARP-binding protein Rtt102. Cryo-EM and biochemical analyses of this subcomplex shows that ARP binding induces a helical conformation in the helicase-SANT-associated (HSA) domain of Sth1. Surprisingly, the ARP module is rotated 120° relative to the full RSC about a pivot point previously identified as a regulatory hub in Sth1, suggesting that large conformational changes are part of Sth1 regulation and RSC assembly. We also show that a conserved interaction between Sth1 and the nucleosome acidic patch enhances remodeling. As some cancer-associated mutations dysregulate rather than inactivate SWI/SNF remodelers, our insights into RSC complex r
