ATF7IP2/MCAF2 directs H3K9 methylation and meiotic gene regulation in the male germline [CUT&RUN, CUT&Tag]

Project description:H3K9 tri-methylation (H3K9me3) plays emerging roles in gene regulation, beyond its accumulation on pericentric constitutive heterochromatin. It remains a mystery why and how H3K9me3 undergoes dynamic regulation in male meiosis. Here, we identify a novel, critical regulator of H3K9 methylation and spermatogenic heterochromatin organization: the germline-specific protein ATF7IP2 (MCAF2). We show that, in male meiosis, ATF7IP2 amasses on autosomal and X pericentric heterochromatin, spreads through the entirety of the sex chromosomes, and accumulates on thousands of autosomal promoters and retrotransposon loci. On the sex chromosomes, which undergo meiotic sex chromosome inactivation (MSCI), the DNA damage response pathway recruits ATF7IP2 to X pericentric heterochromatin, where it facilitates the recruitment of SETDB1, a histone methyltransferase that catalyzes H3K9me3. In the absence of ATF7IP2, male germ cells are arrested in meiotic prophase. Analyses of ATF7IP2-deficient meiosis reveal the protein’s essential roles in the maintenance of MSCI, suppression of retrotransposons, and global activation of autosomal genes. We propose that ATF7IP2 is a downstream effector of the DDR pathway in meiosis that coordinates the organization of heterochromatin and gene regulation through the spatial regulation of SETDB1-mediated H3K9me3 deposition. CUT&RUN of H3K9me3 in Atf7ip2+/+ and Atf7ip2-/- pachytene spermatocytes and CUT&Tag of ATF7IP2 in C57/B6 WT pachytene spermatocytes.

We performed gene expression analysis using data obtained from RNA-seq of Atf7ip2+/+ and Atf7ip2-/- pachytene spermatocytes.

MCAF2/ATF7IP2 directs meiosis-specific H3K9 methylation

Project description:H3K9 tri-methylation (H3K9me3) has emerging functions in gene regulation in addition to its accumulation on constitutive heterochromatin at pericentromeres. It remains a mystery why and how H3K9me3 is dynamically regulated in male meiosis. Here, we identify a novel and critical regulator of H3K9 methylation and spermatogenic heterochromatin organization: the germline-specific protein MCAF2 (ATF7IP2). We show that MCAF2 amasses on autosomal and X pericentric heterochromatin in male germ cells. On the sex chromosomes, which undergo meiotic sex chromosome inactivation (MSCI), the DNA damage response pathway recruits MCAF2 to X pericentric heterochromatin, where it facilitates the recruitment of SETDB1, a histone methyltransferase that catalyzes H3K9me3. In the absence of MCAF2, germ cells are arrested in meiotic prophase, and the mutant analyses revealed that MCAF2 is required for the maintenance of MSCI, and for global activation of autosomal genes and retrotransposon-derived loci in meiosis; this reveals a regulatory function for MCAF2 that is counterintuitive to its association with repressive H3K9me3. Taken together, we propose that MCAF2 is a downstream effector of the DDR pathway in meiosis that coordinates the organization of heterochromatin and gene regulation through the spatial regulation of SETDB1-mediated H3K9me3 deposition.

Here, we identify a novel, critical regulator of H3K9 methylation and spermatogenic heterochromatin organization: the germline-specific protein ATF7IP2 (MCAF2). We show that in male meiosis, ATF7IP2 amasses on autosomal and X-pericentric heterochromatin, spreads through the entirety of the sex chromosomes, and accumulates on thousands of autosomal promoters and retrotransposon loci. On the sex chromosomes, which undergo meiotic sex chromosome inactivation (MSCI), the DNA damage response pathway recruits ATF7IP2 to X-pericentric heterochromatin, where it facilitates the recruitment of SETDB1, a histone methyltransferase that catalyzes H3K9me3. In the absence of ATF7IP2, male germ cells are arrested in meiotic prophase I. Analyses of ATF7IP2-deficient meiosis reveal the protein's essential roles in the maintenance of MSCI, suppression of retrotransposons, and global up-regulation of autosomal genes. We propose that ATF7IP2 is a downstream effector of the DDR pathway in meiosis that coordinates the organization of heterochromatin and gene regulation through the spatial regulation of SETDB1-mediated H3K9me3 deposition.
