STRINGSTRING
SSH4 protein (Saccharomyces cerevisiae) - STRING interaction network
"SSH4" - Specificity factor required for Rsp5p-dependent ubiquitination and sorting of cargo proteins at the multivesicular body in Saccharomyces cerevisiae
Nodes:
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:
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
Others
textmining
co-expression
protein homology

SSH4Specificity factor required for Rsp5p-dependent ubiquitination and sorting of cargo proteins at the multivesicular body; identified as a high-copy suppressor of a SHR3 deletion, increasing steady-state levels of amino acid permeases; Components of the endosome-vacuole trafficking pathway that regulates nutrient transport. May be involved in processes which determine whether plasma membrane proteins are degraded or routed to the plasma membrane. Confers leflunomide resistance when overexpressed (579 aa)    
Predicted Functional Partners:
RMD5
Conserved protein that has an E3-like ubiquitin ligase activity necessary for polyubiquitination and degradation of the gluconeogenic enzyme fructose-1,6-bisphosphatase; also required for sporulation; has a degenerate RING finger domain; Has a role in the negative regulation of gluconeogenesis. Required for proteasome-dependent catabolite degradation of fructose-1,6-bisphosphatase (FBPase). Required specifically for the ubiquitination of FBPase. Also required for sporulation (421 aa)

GID7
Protein of unknown function, involved in proteasome-dependent catabolite inactivation of fructose-1,6-bisphosphatase; contains six WD40 repeats; computational analysis suggests that Gid7p and Moh1p have similar functions; Has a role in the negative regulation of gluconeogenesis. Required for proteasome-dependent catabolite degradation of fructose-1,6-bisphosphatase (FBPase) (745 aa)

GID8
Protein of unknown function, involved in proteasome-dependent catabolite inactivation of fructose-1,6-bisphosphatase; contains LisH and CTLH domains, like Vid30p; dosage-dependent regulator of START; Has a role in the negative regulation of gluconeogenesis. Required for proteasome-dependent catabolite degradation of fructose-1,6-bisphosphatase (FBPase). Required also for cell cycle progression. Positively controls G1 and the timing of START (455 aa)

SHE1
Mitotic spindle protein that interacts with components of the Dam1 (DASH) complex, its effector Sli15p, and microtubule-associated protein Bim1p; also localizes to nuclear microtubules and to the bud neck in a ring-shaped structure; May have a role related to the spindle integrity function of the DAM1 complex, which is essential for proper chromosome segregation. Causes growth arrest when highly overexpressed (338 aa)
       
      0.681
MYO4
One of two type V myosin motors (along with MYO2) involved in actin-based transport of cargos; required for mRNA transport, including ASH1 mRNA, and facilitating the growth and movement of ER tubules into the growing bud along with She3p; Part of the mRNA localization machinery that restricts accumulation of certain proteins to the bud and in the daughter cell. Recruited to specific mRNAs including the ASH1 mRNA, coding for a repressor of the HO endonuclease, via its interaction with SHE3 (1471 aa)
       
      0.681
MYO2
One of two type V myosin motors (along with MYO4) involved in actin-based transport of cargos; required for the polarized delivery of secretory vesicles, the vacuole, late Golgi elements, peroxisomes, and the mitotic spindle; Myosin heavy chain that is required for the cell cycle- regulated transport of various organelles and proteins for their segregation. Functions by binding with its tail domain to receptor proteins on organelles and exerting force with its N-terminal motor domain against actin filaments, thereby transporting its cargo along polarized actin cables. Essential for the [...] (1574 aa)

SHR3
Endoplasmic reticulum packaging chaperone, required for incorporation of amino acid permeases into COPII coated vesicles for transport to the cell surface; Involved in amino acid permease processing and required for the efficient translocation of structurally related amino acid permeases from the endoplasmic reticulum to the plasma membrane. SHR3 may function as a permease-specific "adaptor" molecule that functions in conjunction with the SEC62/SEC63 complex. Yeast cells may require SHR3 to expedite the processing of permeases to ensure their rapid expression at the plasma membrane in [...] (210 aa)
       
 
  0.677
ATG33
Mitochondrial mitophagy-specific protein; required primarily for mitophagy induced at the post-log phase; not required for other types of selective autophagy or macroautophagy; conserved within fungi, but not in higher eukaryotes; Involved in the selective degradation of mitochondria via autophagy during starvation and at post-log phase (197 aa)

NIP100
Large subunit of the dynactin complex, which is involved in partitioning the mitotic spindle between mother and daughter cells; putative ortholog of mammalian p150(glued); Motor-binding component of the dynactin complex which assists cytoplasmic dynein by increasing its processivity and by regulation of its cargo binding (By similarity). The dynactin complex is required for the spindle translocation late in anaphase and is involved in a cell wall synthesis checkpoint (868 aa)
