FunFam 19: Myosin heavy chain, isoform G

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 5 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.

Skeletal muscle thin filament assembly GO:0030240
The aggregation, arrangement and bonding together of proteins to form the actin-based thin filaments of myofibrils in skeletal muscle.
2 A4IGA2 (/IMP) B1WB81 (/IMP)
Slow-twitch skeletal muscle fiber contraction GO:0031444
A process in which force is generated within slow-twitch 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. The slow-twitch skeletal muscle is characterized by slow time parameters, low force development and resistance to fatigue.

1 A9JT78 (/IEP)
Extraocular skeletal muscle development GO:0002074
The process whose specific outcome is the progression of the extraocular skeletal muscle over time, from its formation to the mature structure. The extraocular muscle is derived from cranial mesoderm and controls eye movements. The muscle begins its development with the differentiation of the muscle cells and ends with the mature muscle. An example of this process is found in Mus musculus.
1 A0A0G2JY53 (/IEP)
Muscle contraction GO:0006936
A process in which force is generated within 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.
1 P05661 (/IMP)
Border follicle cell migration GO:0007298
The directed movement of a border cell through the nurse cells to reach the oocyte. An example of this is found in Drosophila melanogaster.
1 P05661 (/IMP)
Epithelial cell migration, open tracheal system GO:0007427
The orderly movement of epithelial cells during development of an open tracheal system. An example of this is found in Drosophila melanogaster.
1 P05661 (/IMP)
Muscle organ development GO:0007517
The process whose specific outcome is the progression of the muscle over time, from its formation to the mature structure. The muscle is an organ consisting of a tissue made up of various elongated cells that are specialized to contract and thus to produce movement and mechanical work.
1 P05661 (/IMP)
Adult somatic muscle development GO:0007527
The process whose specific outcome is the progression of the adult somatic muscle over time, from its formation to the mature structure.
1 P05661 (/IMP)
