Phosphorylation of luminal region of the SUN-domain protein Mps3 promotes nuclear envelope localization during meiosis.
Title: Phosphorylation of luminal region of the SUN-domain protein Mps3 promotes nuclear envelope localization during meiosis.
Mps2 links Csm4 and Mps3 to form a telomere-associated LINC complex in budding yeast.
Title: Mps2 links Csm4 and Mps3 to form a telomere-associated LINC complex in budding yeast.
Cdh1, a coactivator of APC/C, modulates Mps3 stability. APC/C controls Mps3 degradation through Mps3's N terminus, which resides in the nucleoplasm and possesses two putative APC/C-dependent destruction motifs.
Title: The anaphase-promoting complex regulates the degradation of the inner nuclear membrane protein Mps3.
the response to a secretory defect required SUN protein Mps3, which was localized at the nuclear envelope and involved in spindle pole body assembly
Title: Arp2/3 complex and Mps3 are required for regulation of ribosome biosynthesis in the secretory stress response.
We show that noncleavable Mps3 (Mps3-nc) inhibits centrosome separation during yeast meiosis. In addition, overexpression of mps3-nc in vegetative yeast cells also inhibits centrosome separation and is lethal
Title: Cleavage of the SUN-domain protein Mps3 at its N-terminus regulates centrosome disjunction in budding yeast meiosis.
Mps2-Bbp1 directly interacts with Mps3 and Ndc1. We then purified Spc29 and reconstituted the ternary Mps2-Bbp1-Spc29 complex, proving that Bbp1 can simultaneously interact with Mps2 and Spc29 and in this way link the central plaque of the spindle pole body to the nuclear envelope
Title: A ternary membrane protein complex anchors the spindle pole body in the nuclear envelope in budding yeast.
TFIIIC and Mps3 together direct the intranuclear positioning of a new class of S. cerevisiae genomic loci positioned at the nuclear periphery.
Title: TFIIIC localizes budding yeast ETC sites to the nuclear periphery.
Acetylation of Mps3 by Eco1 is one of the few regulatory mechanisms known to control nuclear organization.
Title: Acetylation of the SUN protein Mps3 by Eco1 regulates its function in nuclear organization.
we propose that Mps3 facilitates insertion of SPBs(spindle pole body) in the nuclear membrane by modulating nuclear envelope composition.
Title: The SUN protein Mps3 is required for spindle pole body insertion into the nuclear membrane and nuclear envelope homeostasis.
These findings suggest that in meiosis, the Mps3 SUN domain is important for modulating chromosome motion events that act in meiotic chromosome juxtaposition and by extension, promoting proper morphogenesis of the synaptonemal complex.
Title: Mps3 SUN domain is important for chromosome motion and juxtaposition of homologous chromosomes during meiosis.
