MNS1 protein (Saccharomyces cerevisiae) - STRING interaction network
"MNS1" - Alpha-1,2-mannosidase involved in ER quality control in Saccharomyces cerevisiae
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
protein homology

MNS1Alpha-1,2-mannosidase involved in ER quality control; catalyzes the removal of one mannose residue from Man9GlcNAc to produce a single isomer of Man8GlcNAc in N-linked oligosaccharide biosynthesis; integral to ER membrane; Involved in glycoprotein quality control as it is important for the targeting of misfolded glycoproteins for degradation. It primarily trims a single alpha-1,2-linked mannose residue from Man(9)GlcNAc(2) to produce Man(8)GlcNAc(2), but at high enzyme concentrations it further trims the carbohydrates to Man(5)GlcNAc(2) (549 aa)    
Predicted Functional Partners:
Mannosyltransferase of the cis-Golgi apparatus, initiates the polymannose outer chain elongation of N-linked oligosaccharides of glycoproteins; Mannosyltransferase involved in outer chain elongation of asparagine-linked oligosaccharides of the type Man(9)GlcNAc(2). Adds the first alpha-1,6-mannose to the Man(8)GlNAc(2) and Man(9)GlcNAc(2), but not Man(5)GlcNAc(2), endoplasmic reticulum intermediates. Represents the first enzymatic event required for synthesis of outer chain mannose linkages on yeast secretory proteins. Has also the potential to transfer a second alpha-1,6- mannose to t [...] (480 aa)
Glucosidase II catalytic subunit required for normal cell wall synthesis; mutations in rot2 suppress tor2 mutations, and are synthetically lethal with rot1 mutations; Catalytic subunit of glucosidase 2, which cleaves sequentially the 2 innermost alpha-1,3-linked glucose residues from the Glc(2)Man(9)GlcNAc(2) oligosaccharide precursor of immature glycoproteins (954 aa)
Putative mannosidase involved in ER-associated protein degradation; localizes to the endoplasmic reticulum; sequence similarity with seven-hairpin glycosidase (GH47) family members, such as Mns1p and Mnl1p, that hydrolyze 1,2-linked alpha-D-mannose /.../es; non-essential gene; Putative mannosidase involved in glycoprotein quality control since it is involved in the targeting of misfolded glycoproteins for ER-associated protein degradation (ERAD) (849 aa)
Protein involved in retention of membrane proteins, including Sec12p, in the ER; localized to Golgi; functions as a retrieval receptor in returning membrane proteins to the ER; Involved in the retrieval of endoplasmic reticulum membrane proteins from the early Golgi compartment. Required for correct localization of SEC12, SEC71 and SEC63 in the endoplasmic reticulum (188 aa)
Component of the spindle pole body outer plaque, required for exit from mitosis; Involved in astral microtubule organization by binding SCP72 to the outer plaque in a cell-cycle dependent manner. Required for the mitotic exit by facilitating the binding of TEMP1 to CDC15. Also involved in the pathway that organizes the shaping and sizing of the prospore membrane (PSM) during sporulation (851 aa)
Negative regulatory subunit of protein phosphatase 1 Ppz1p and also a subunit of the phosphopantothenoylcysteine decarboxylase (PPCDC; Cab3p, Sis2p, Vhs3p) complex, which catalyzes the third step of coenzyme A biosynthesis; Component of the phosphopantothenoylcysteine decarboxylase (PPCDC) involved in the coenzyme A synthesis. Acts as an inhibitory subunit of protein phosphatase PPZ1, which is involved in many cellular processes such as G1-S transition or salt tolerance. Also modulates the expression of the ENA1 ATPase (562 aa)
tRNA methyltransferase, 5-methylates the uridine residue at position 54 of tRNAs and may also have a role in tRNA stabilization or maturation; endo-exonuclease with a role in DNA repair; Catalyzes the formation of 5-methyl-uridine at position 54 (m5U54) in all tRNA. May also have a role in tRNA stabilization or maturation (639 aa)
DNA-dependent ATPase, stimulates strand exchange by modifying the topology of double-stranded DNA; involved in recombinational repair of DNA double-strand breaks during mitosis and meiosis; proposed to be involved in crossover interference; Involved in the recombinational repair of double-strand breaks (DSB) in DNA during mitosis and meiosis. Has DNA dependent ATPase activity. Promotes D-loop (displacement loop) formation with RAD51 recombinase. Modifies the topology of double-stranded DNA during the D-loop reaction to facilitate the invasion of the homologous duplex molecule by the in [...] (958 aa)
Vacuolar alpha mannosidase, involved in free oligosaccharide (fOS) degradation; delivered to the vacuole in a novel pathway separate from the secretory pathway; Degrades free oligosaccharides in the vacuole (1083 aa)
Dolichol-P-Man dependent alpha(1-3) mannosyltransferase, involved in the synthesis of dolichol-linked oligosaccharide donor for N-linked glycosylation of proteins; Adds the first Dol-P-Man derived mannose in an alpha-1,3 linkage to Man(5)GlcNAc(2)-PP-Dol. Sensitive to H.mrakii HM-1 killer toxin (458 aa)
