FunFam 22: SH3 and cysteine-rich domain-containing protein 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 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
Positive regulation of voltage-gated calcium channel activity GO:1901387
Any process that activates or increases the frequency, rate or extent of voltage-gated calcium channel activity.

Skeletal muscle contraction GO:0003009
A process in which force is generated within skeletal muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. In the skeletal muscle, the muscle contraction takes advantage of an ordered sarcomeric structure and in most cases it is under voluntary control.

Skeletal muscle contraction GO:0003009
A process in which force is generated within skeletal muscle tissue, resulting in a change in muscle geometry. Force generation involves a chemo-mechanical energy conversion step that is carried out by the actin/myosin complex activity, which generates force through ATP hydrolysis. In the skeletal muscle, the muscle contraction takes advantage of an ordered sarcomeric structure and in most cases it is under voluntary control.
2 Q68F99 (/ISS) Q8BZ71 (/ISS)
Neuromuscular synaptic transmission GO:0007274
The process of synaptic transmission from a neuron to a muscle, across a synapse.
2 Q96MF2 (/IMP) Q96MF2 (/IMP)
Neuromuscular synaptic transmission GO:0007274
The process of synaptic transmission from a neuron to a muscle, across a synapse.
2 Q68F99 (/ISS) Q8BZ71 (/ISS)
Positive regulation of voltage-gated calcium channel activity GO:1901387

Skeletal muscle tissue development GO:0007519
The developmental sequence of events leading to the formation of adult skeletal muscle tissue. The main events are: the fusion of myoblasts to form myotubes that increase in size by further fusion to them of myoblasts, the formation of myofibrils within their cytoplasm and the establishment of functional neuromuscular junctions with motor neurons. At this stage they can be regarded as mature muscle fibers.
1 Q6DBR6 (/IMP)
Regulation of release of sequestered calcium ion into cytosol by sarcoplasmic reticulum GO:0010880
Any process that modulates the rate, frequency or extent of release of sequestered calcium ion into cytosol by the sarcoplasmic reticulum, the process in which the release of sequestered calcium ion by sarcoplasmic reticulum into cytosol occurs via calcium release channels.
1 Q6DBR6 (/IMP)
T-tubule organization GO:0033292
A process that is carried out at the cellular level that results in the assembly, arrangement of constituent parts, or disassembly of the T-tubule. A T-tubule is an invagination of the plasma membrane of a muscle cell that extends inward from the cell surface around each myofibril.
1 Q6DBR6 (/IMP)
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.
