FunFam 29: GD10048

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 4 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
SNARE binding GO:0000149
Interacting selectively and non-covalently with a SNARE (soluble N-ethylmaleimide-sensitive factor attached protein receptor) protein.
1 Q7JYX5 (/IPI)
SNAP receptor activity GO:0005484
Acting as a marker to identify a membrane and interacting selectively with one or more SNAREs on another membrane to mediate membrane fusion.
1 Q7JYX5 (/IC)
SNAP receptor activity GO:0005484
Acting as a marker to identify a membrane and interacting selectively with one or more SNAREs on another membrane to mediate membrane fusion.
1 Q7JYX5 (/IPI)
Syntaxin binding GO:0019905
Interacting selectively and non-covalently with a syntaxin, a SNAP receptor involved in the docking of synaptic vesicles at the presynaptic zone of a synapse.
1 Q7JYX5 (/ISS)

There are 3 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
Vesicle fusion GO:0006906
Fusion of the membrane of a transport vesicle with its target membrane.
1 Q7JYX5 (/ISS)
Endosome to lysosome transport GO:0008333
The directed movement of substances from endosomes to lysosomes.
1 Q7JYX5 (/ISS)
Autophagosome maturation GO:0097352
Removal of PI3P and Atg8/LC3 after the closure of the phagophore and before the fusion with the endosome/lysosome (e.g. mammals and insects) or vacuole (yeast), and that very likely destabilizes other Atg proteins and thus enables their efficient dissociation and recycling.
1 Q7JYX5 (/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
SNARE complex GO:0031201
A protein complex involved in membrane fusion; a stable ternary complex consisting of a four-helix bundle, usually formed from one R-SNARE and three Q-SNAREs with an ionic layer sandwiched between hydrophobic layers. One well-characterized example is the neuronal SNARE complex formed of synaptobrevin 2, syntaxin 1a, and SNAP-25.
1 Q7JYX5 (/IDA)
SNARE complex GO:0031201
A protein complex involved in membrane fusion; a stable ternary complex consisting of a four-helix bundle, usually formed from one R-SNARE and three Q-SNAREs with an ionic layer sandwiched between hydrophobic layers. One well-characterized example is the neuronal SNARE complex formed of synaptobrevin 2, syntaxin 1a, and SNAP-25.
1 Q7JYX5 (/ISS)
Late endosome membrane GO:0031902
The lipid bilayer surrounding a late endosome.
1 Q7JYX5 (/ISS)
Autolysosome GO:0044754
A type of secondary lysosome in which a primary lysosome has fused with the outer membrane of an autophagosome. It is involved in the second step of autophagy in which it degrades contents with acidic lysosomal hydrolases.
