Control of Locomotory Behavior of Caenorhabditis elegans by the Immunoglobulin Superfamily Protein RIG-3.

abstract：:Chromatin organization and structure are crucial for transcriptional regulation, DNA replication, and damage repair. Although initially characterized in remodeling cell wall glucans, the β-1,3-glucanosyltransferase Gas1 was recently discovered to regulate transcriptional silencing in a manner separable from its activi...

abstract：:Spt3 of Saccharomyces cerevisiae is required for the normal transcription of many genes in vivo. Past studies have shown that Spt3 is required for both mating and sporulation, two events that initiate when cells are at G(1)/START. We now show that Spt3 is needed for two other events that begin at G(1)/START, diploid f...
