The name of this superfamily has been modified since the most recent official CATH+ release (v4_3_0). At the point of the last release, this superfamily was named:
"Calponin-like domain
".
FunFam 130: Actinin alpha 1
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 3 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 |
|---|---|---|
|
Vinculin binding GO:0017166
Interacting selectively and non-covalently with vinculin, a protein found in muscle, fibroblasts, and epithelial cells that binds actin and appears to mediate attachment of actin filaments to integral proteins of the plasma membrane.

1 | F7DZI2 (/ISS) |
|
Protein homodimerization activity GO:0042803
Interacting selectively and non-covalently with an identical protein to form a homodimer.

|
Alpha-actinin binding GO:0051393
Interacting selectively and non-covalently with alpha-actinin, one of a family of proteins that cross-link F-actin as antiparallel homodimers. Alpha-actinin has a molecular mass of 93-103 KDa; at the N-terminus there are two calponin homology domains, at the C-terminus there are two EF-hands. These two domains are connected by the rod domain. This domain is formed by triple-helical spectrin repeats.

Sarcomere organization GO:0045214
The myofibril assembly process that results in the organization of muscle actomyosin into sarcomeres. The sarcomere is the repeating unit of a myofibril in a muscle cell, composed of an array of overlapping thick and thin filaments between two adjacent Z discs.

1 | F7DZI2 (/ISS) |
|
Skeletal muscle fiber development GO:0048741
The process whose specific outcome is the progression of the skeletal muscle fiber over time, from its formation to the mature structure. Muscle fibers are formed by the maturation of myotubes. They can be classed as slow, intermediate/fast or fast.

|
Stress fiber GO:0001725
A contractile actin filament bundle that consists of short actin filaments with alternating polarity, cross-linked by alpha-actinin and possibly other actin bundling proteins, and with myosin present in a periodic distribution along the fiber.
|
1 | F7DZI2 (/ISS) |
|
Zonula adherens GO:0005915
A cell-cell adherens junction which forms a continuous belt near the apex of epithelial cells.
|
1 | F7DZI2 (/ISS) |
|
Bicellular tight junction GO:0005923
An occluding cell-cell junction that is composed of a branching network of sealing strands that completely encircles the apical end of each cell in an epithelial sheet; the outer leaflets of the two interacting plasma membranes are seen to be tightly apposed where sealing strands are present. Each sealing strand is composed of a long row of transmembrane adhesion proteins embedded in each of the two interacting plasma membranes.

|
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 | F7DZI2 (/ISS) |
|
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 | F7DZI2 (/ISS) |
|
Lamellipodium GO:0030027
A thin sheetlike process extended by the leading edge of a migrating cell or extending cell process; contains a dense meshwork of actin filaments.
|
1 | F7DZI2 (/ISS) |
|
Smooth muscle dense body GO:0030486
Electron-dense region associated with a smooth muscle contractile fiber.

|
Outer dense plaque of desmosome GO:0090636
The desmosomal part containing plakoglobins, plakophilins, the N-termini of desmoplakins, as well as the cytoplasmic tails of the desmosomal cadherins, which together attach the plaque to the plasma membrane.
|
1 | F7DZI2 (/ISS) |
|
Inner dense plaque of desmosome GO:0090637
The desmosomal part containing the C-termini of desmoplakins which interact with the keratin intermediate filaments, serving to tether the intermediate filaments to the plasma membrane.
|
1 | F7DZI2 (/ISS) |
|
Dense body GO:0097433
An electron dense body which may contain granules.
|
1 | F7DZI2 (/ISS) |
|
Terminal web GO:1990357
An actin-rich cytoskeletal network located beneath the microvilli of the apical plasma membrane of polarized epithelial cells. In addition to actin filaments, the terminal web may contain actin-binding proteins, myosin motor proteins, and intermediate filaments. The terminal web can function as a contractile structure that influences the spatial distribution of microvilli as well as the development and morphogenesis of tissues containing polarized epithelial cells.
