FunFam 49: MAGUK p55 subfamily member 5

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
Morphogenesis of an epithelial sheet GO:0002011

1 Q8N3R9 (/IMP)
Morphogenesis of an epithelial sheet GO:0002011
The process in which the anatomical structures of an epithelial sheet are generated and organized. An epithelial sheet is a flat surface consisting of closely packed epithelial cells.
1 Q9JLB2 (/ISO)
Plasma membrane organization GO:0007009
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of the plasma membrane.
1 Q9JLB2 (/IMP)
Peripheral nervous system myelin maintenance GO:0032287
The process in which the structure and material content of mature peripheral nervous system myelin is kept in a functional state.
1 Q9JLB2 (/IMP)
Myelin assembly GO:0032288
The process in which the wraps of cell membrane that constitute myelin are laid down around an axon in the central or peripheral nervous system.
1 B4F7E7 (/IMP)
Protein localization to myelin sheath abaxonal region GO:0035750
Any process in which a protein is transported to, and/or maintained in, the abaxonal region of the myelin sheath. The abaxonal region is the region of the myelin sheath furthest from the axon.
1 Q9JLB2 (/IMP)
Bicellular tight junction assembly GO:0070830

Establishment of protein localization to plasma membrane GO:0090002
The directed movement of a protein to a specific location in the plasma membrane.
1 B4F7E7 (/IMP)

GO Term Annotations Evidence
Cytoplasm GO:0005737

1 Q8N3R9 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 Q9JLB2 (/ISO)
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
1 Q9JLB2 (/IDA)
Plasma membrane GO:0005886

1 Q9JLB2 (/ISS)
Myelin sheath adaxonal region GO:0035749
The region of the myelin sheath nearest to the axon.
1 Q9JLB2 (/IDA)
Lateral loop GO:0043219
Non-compact myelin located adjacent to the nodes of Ranvier in a myelin segment. These non-compact regions include cytoplasm from the cell responsible for synthesizing the myelin. Lateral loops are found in the paranodal region adjacent to the nodes of Ranvier, while Schmidt-Lantermann clefts are analogous structures found within the compact myelin internode.
1 Q9JLB2 (/IDA)
Schmidt-Lanterman incisure GO:0043220
Regions within compact myelin in which the cytoplasmic faces of the enveloping myelin sheath are not tightly juxtaposed, and include cytoplasm from the cell responsible for making the myelin. Schmidt-Lanterman incisures occur in the compact myelin internode, while lateral loops are analogous structures found in the paranodal region adjacent to the nodes of Ranvier.
1 Q9JLB2 (/IDA)
Protein complex GO:0043234
A stable macromolecular complex composed (only) of two or more polypeptide subunits along with any covalently attached molecules (such as lipid anchors or oligosaccharide) or non-protein prosthetic groups (such as nucleotides or metal ions). Prosthetic group in this context refers to a tightly bound cofactor. The component polypeptide subunits may be identical.
1 B4F7E7 (/IDA)
Extracellular exosome GO:0070062
