FunFam 36: Sushi repeat containing protein X-linked

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 2 GO terms relating to "molecular function"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
4 P78539 (/IPI) P78539 (/IPI) P78539 (/IPI) Q9R0M3 (/IPI)
Extracellular matrix structural constituent GO:0005201
The action of a molecule that contributes to the structural integrity of the extracellular matrix.
3 P78539 (/RCA) P78539 (/RCA) P78539 (/RCA)

There are 5 GO terms relating to "biological process"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Phagolysosome assembly GO:0001845
The process that results in the fusion of a phagosome, a vesicle formed by phagocytosis, with a lysosome.
1 Q9R0M3 (/IMP)
Autophagy GO:0006914
The cellular catabolic process in which cells digest parts of their own cytoplasm; allows for both recycling of macromolecular constituents under conditions of cellular stress and remodeling the intracellular structure for cell differentiation.
1 Q9R0M3 (/IMP)
Response to endoplasmic reticulum stress GO:0034976
Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stress acting at the endoplasmic reticulum. ER stress usually results from the accumulation of unfolded or misfolded proteins in the ER lumen.
1 Q9R0M3 (/IMP)
Negative regulation of cell proliferation involved in contact inhibition GO:0060244
Any process that stops, prevents or reduces the rate or extent of cell proliferation in response to cell density.
1 Q9R0M3 (/IDA)
Positive regulation of extrinsic apoptotic signaling pathway in absence of ligand GO:2001241
Any process that activates or increases the frequency, rate or extent of extrinsic apoptotic signaling pathway in absence of ligand.
1 Q9R0M3 (/IMP)

There are 4 GO terms relating to "cellular component"

The search results have been sorted with the annotations that are found most frequently at the top of the list. The results can be filtered by typing text into the search box at the top of the table.
GO Term Annotations Evidence
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
3 P78539 (/TAS) P78539 (/TAS) P78539 (/TAS)
Collagen-containing extracellular matrix GO:0062023
An extracellular matrix consisting mainly of proteins (especially collagen) and glycosaminoglycans (mostly as proteoglycans) that provides not only essential physical scaffolding for the cellular constituents but can also initiate crucial biochemical and biomechanical cues required for tissue morphogenesis, differentiation and homeostasis. The components are secreted by cells in the vicinity and form a sheet underlying or overlying cells such as endothelial and epithelial cells.
3 P78539 (/HDA) P78539 (/HDA) P78539 (/HDA)
Autophagosome GO:0005776
A double-membrane-bounded compartment that engulfs endogenous cellular material as well as invading microorganisms to target them to the lytic vacuole/lysosome for degradation as part of macroautophagy.
1 Q9R0M3 (/IDA)
Endoplasmic reticulum GO:0005783
The irregular network of unit membranes, visible only by electron microscopy, that occurs in the cytoplasm of many eukaryotic cells. The membranes form a complex meshwork of tubular channels, which are often expanded into slitlike cavities called cisternae. The ER takes two forms, rough (or granular), with ribosomes adhering to the outer surface, and smooth (with no ribosomes attached).
