FunFam 199: Na(+)/H(+) exchange regulatory cofactor NHE-RF4

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 9 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
Ion transport GO:0006811
The directed movement of charged atoms or small charged molecules into, out of or within a cell, or between cells, by means of some agent such as a transporter or pore.
1 Q86UT5 (/NAS)
Water transport GO:0006833

1 Q86UT5 (/NAS)
Receptor guanylyl cyclase signaling pathway GO:0007168
A series of molecular signals initiated by the binding of an extracellular ligand to a receptor on the surface of the target cell where the receptor possesses guanylyl cyclase activity, and ending with regulation of a downstream cellular process, e.g. transcription.
1 Q86UT5 (/IC)
Response to toxic substance GO:0009636

There are 9 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
Brush border GO:0005903
The dense covering of microvilli on the apical surface of a epithelial cells in tissues such as the intestine, kidney, and choroid plexus; the microvilli aid absorption by increasing the surface area of the cell.
2 Q86UT5 (/IDA) Q99MJ6 (/IDA)
Apical part of cell GO:0045177
The region of a polarized cell that forms a tip or is distal to a base. For example, in a polarized epithelial cell, the apical region has an exposed surface and lies opposite to the basal lamina that separates the epithelium from other tissue.
2 Q86UT5 (/IDA) Q99MJ6 (/IDA)
Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 Q99MJ6 (/IDA)
Cytosol GO:0005829

1 Q86UT5 (/TAS)
Brush border GO:0005903
