Yeast X-Chromosome Associated Protein 5 (Xap5) Functions with H2A.Z to Suppress Aberrant Transcripts [RNA-seq]


ABSTRACT: Functional characterization of the Xap5 protein using epistatic genetic interaction analysis (E-MAP), RNA-seq and ChIP-chip along with other growth experiments. wild type and mutant cells were grown at 37C in EMM50 and RNA was extracted from exponentially growing cells. Strand specific libraries were constructed with random primers. Ribo zero was used to remove r-RNA. For ChIP-chip Agilent 60mer array was used to analyze DNA recovered by chromatin immunoprecipitation of Xap5 from fission yeast culture.

Chromatin regulatory proteins affect diverse developmental and environmental response pathways via their influence on nuclear processes such as the regulation of gene expression. Through a genome-wide genetic screen, we implicate a novel protein called X-chromosome-associated protein 5 (Xap5) in chromatin regulation. We show that Xap5 is a chromatin-associated protein acting in a similar manner as the histone variant H2A.Z to suppress expression of antisense and repeat element transcripts throug  ...[more]
