FunFam 156: Myosin heavy chain subunit

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
Microfilament motor activity GO:0000146
Catalysis of movement along a microfilament, coupled to the hydrolysis of a nucleoside triphosphate (usually ATP).
2 Q8IHW0 (/ISS) Q8IHW0 (/ISS)
Motor activity GO:0003774
Catalysis of the generation of force resulting either in movement along a microfilament or microtubule, or in torque resulting in membrane scission, coupled to the hydrolysis of a nucleoside triphosphate.
2 Q8IHW0 (/ISS) Q8IHW0 (/ISS)
Actin binding GO:0003779
Interacting selectively and non-covalently with monomeric or multimeric forms of actin, including actin filaments.

There are 2 GO terms relating to "biological process"

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
Cytoskeleton organization GO:0007010
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of cytoskeletal structures.
2 Q8IHW0 (/ISS) Q8IHW0 (/ISS)
Actin filament-based movement GO:0030048
Movement of organelles or other particles along actin filaments, or sliding of actin filaments past each other, mediated by motor proteins.
2 Q8IHW0 (/ISS) Q8IHW0 (/ISS)

There are 1 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
Myosin complex GO:0016459
A protein complex, formed of one or more myosin heavy chains plus associated light chains and other proteins, that functions as a molecular motor; uses the energy of ATP hydrolysis to move actin filaments or to move vesicles or other cargo on fixed actin filaments; has magnesium-ATPase activity and binds actin. Myosin classes are distinguished based on sequence features of the motor, or head, domain, but also have distinct tail regions that are believed to bind specific cargoes.
