FunFam 13: Putative Sorting nexin 3

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
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).

Phosphatidylinositol-3-phosphate binding GO:0032266
Interacting selectively and non-covalently with phosphatidylinositol-3-phosphate, a derivative of phosphatidylinositol in which the inositol ring is phosphorylated at the 3' position.

Phosphatidylinositol binding GO:0035091
Interacting selectively and non-covalently with any inositol-containing glycerophospholipid, i.e. phosphatidylinositol (PtdIns) and its phosphorylated derivatives.

Identical protein binding GO:0042802
Interacting selectively and non-covalently with an identical protein or proteins.

Retrograde transport, endosome to Golgi GO:0042147
The directed movement of membrane-bounded vesicles from endosomes back to the trans-Golgi network where they are recycled for further rounds of transport.
3 Q92331 (/IPI) Q92331 (/IPI) Q92331 (/IPI)
Protein retention in Golgi apparatus GO:0045053
The retention of proteins within the Golgi apparatus. Golgi-localized carbohydrate-modifying enzymes have a short N-terminal domain that faces the cytosol, a single transmembrane alpha helix, and a large C-terminal domain that faces the Golgi lumen and that contains the catalytic site. How the membrane-spanning alpha helix in a Golgi enzyme causes its localization and prevents its movement to the plasma membrane is not known.
3 Q92331 (/IMP) Q92331 (/IMP) Q92331 (/IMP)
Intracellular protein transport GO:0006886
The directed movement of proteins in a cell, including the movement of proteins between specific compartments or structures within a cell, such as organelles of a eukaryotic cell.
1 Q9C0U7 (/IMP)
Vesicle-mediated transport GO:0016192
A cellular transport process in which transported substances are moved in membrane-bounded vesicles; transported substances are enclosed in the vesicle lumen or located in the vesicle membrane. The process begins with a step that directs a substance to the forming vesicle, and includes vesicle budding and coating. Vesicles are then targeted to, and fuse with, an acceptor membrane.
1 Q9C0U7 (/IMP)
Ascospore-type prospore membrane assembly GO:0032120
The process in which the nascent membrane forms at the meiotic outer plaque and grows until closure occurs and forespores, or prospores, are formed.
1 Q9C0U7 (/IMP)
Retrograde transport, endosome to Golgi GO:0042147
The directed movement of membrane-bounded vesicles from endosomes back to the trans-Golgi network where they are recycled for further rounds of transport.

GO Term Annotations Evidence
Retromer complex GO:0030904
A conserved hetero-pentameric membrane-associated complex involved in retrograde transport from endosomes to the Golgi apparatus. The budding yeast retromer comprises Vps35p, Vps29p, Vps26p, Vps5p, and Vps17p. The mammalian complex shows slight variation in composition compared to yeast, and comprises SNX1 or SNX2, SNX5 or SNX6, VPS26A or VPS26B, VPS29, and VPS35.

Endosome GO:0005768
A vacuole to which materials ingested by endocytosis are delivered.
3 Q92331 (/IDA) Q92331 (/IDA) Q92331 (/IDA)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

Retromer, tubulation complex GO:0030905
The dimeric subcomplex of the retromer, believed to be peripherally associated with the membrane. This dimeric complex is responsible for remodelling endosomal membranes to form a tube-structure to which cargo molecules are selected for recycling. The budding yeast complex comprises Vps5p and Vps17p, and may contain multiple copies of a Vps5p/Vps17p dimer. The mammalian complex contains SNX1 or SNX2 dimerized with SNX5 or SNX6.

Prospore membrane GO:0005628
The prospore membrane is a double-membraned structure that extends from the cytoplasmic face of the spindle pole bodies to encompass the spindle pole bodies and the four nuclear lobes that are formed during meiosis. It helps isolate the meiotic nuclei from the cytoplasm during spore formation and serves as a foundation for the formation of the spore walls. An example of this component is found in Schizosaccharomyces pombe.

Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
