FunFam 6104: Testin isoform 1 variant

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 12 GO terms relating to "molecular function"

Cytoplasm GO:0005737
All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.
1 A1Z6W3 (/TAS)
Cytosol GO:0005829
The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.
1 Q96MT3 (/TAS)
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 P47226 (/ISO)
Focal adhesion GO:0005925
Small region on the surface of a cell that anchors the cell to the extracellular matrix and that forms a point of termination of actin filaments.
1 P47226 (/ISO)
Cell cortex GO:0005938
The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.
1 Q7ZXE9 (/IDA)
Cell cortex GO:0005938
The region of a cell that lies just beneath the plasma membrane and often, but not always, contains a network of actin filaments and associated proteins.
1 Q6DIR5 (/ISS)
Actin cytoskeleton GO:0015629
The part of the cytoskeleton (the internal framework of a cell) composed of actin and associated proteins. Includes actin cytoskeleton-associated complexes.
1 A1ZAT5 (/IDA)
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
1 A1Z6W3 (/NAS)
Apicolateral plasma membrane GO:0016327
The apical end of the lateral plasma membrane of epithelial cells.
1 Q80Y24 (/IDA)
Lateral plasma membrane GO:0016328
The portion of the plasma membrane at the lateral side of the cell. In epithelial cells, lateral plasma membranes are on the sides of cells which lie at the interface of adjacent cells.
1 Q80Y24 (/IDA)
Cell junction GO:0030054
A cellular component that forms a specialized region of connection between two or more cells or between a cell and the extracellular matrix. At a cell junction, anchoring proteins extend through the plasma membrane to link cytoskeletal proteins in one cell to cytoskeletal proteins in neighboring cells or to proteins in the extracellular matrix.
1 P47226 (/ISO)
Nuclear membrane GO:0031965
Either of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space.
1 Q96MT3 (/IDA)
Nuclear membrane GO:0031965
Either of the lipid bilayers that surround the nucleus and form the nuclear envelope; excludes the intermembrane space.
1 Q3U5C7 (/ISO)
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 Q9UGI8 (/IDA)
