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 7 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
Skeletal system development GO:0001501
The process whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure. The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton).
2 Q7TQN3 (/IGI) Q8R0S6 (/IGI)
Negative regulation of transforming growth factor beta receptor signaling pathway GO:0030512
Any process that stops, prevents, or reduces the frequency, rate or extent of any TGF-beta receptor signaling pathway.
2 Q8TEU8 (/IDA) Q96NZ8 (/IDA)
Negative regulation of transforming growth factor beta receptor signaling pathway GO:0030512
Any process that stops, prevents, or reduces the frequency, rate or extent of any TGF-beta receptor signaling pathway.
2 Q7TQN3 (/ISO) Q8R0S6 (/ISO)
Negative regulation of protein binding GO:0032091
Any process that stops, prevents, or reduces the frequency, rate or extent of protein binding.
2 Q7TQN3 (/IDA) Q8R0S6 (/IDA)
Negative regulation of DNA binding GO:0043392
Any process that stops or reduces the frequency, rate or extent of DNA binding. DNA binding is any process in which a gene product interacts selectively with DNA (deoxyribonucleic acid).
2 Q7TQN3 (/IDA) Q8R0S6 (/IDA)
Muscle fiber development GO:0048747
The process whose specific outcome is the progression of the muscle fiber over time, from its formation to the mature structure. In skeletal muscle, fibers are formed by the maturation of myotubes. They can be classed as slow, intermediate/fast or fast.
2 Q7TQN3 (/IMP) Q8R0S6 (/IMP)
Roof of mouth development GO:0060021
The biological process whose specific outcome is the progression of the roof of the mouth from an initial condition to its mature state. This process begins with the formation of the structure and ends with the mature structure. The roof of the mouth is the partition that separates the nasal and oral cavities.
2 Q7TQN3 (/IGI) Q8R0S6 (/IGI)
Cell morphogenesis GO:0000902
The developmental process in which the size or shape of a cell is generated and organized.
1 O76840 (/IMP)
Nematode larval development GO:0002119
The process whose specific outcome is the progression of the nematode larva over time, from its formation to the mature structure. Nematode larval development begins with the newly hatched first-stage larva (L1) and ends with the end of the last larval stage (for example the fourth larval stage (L4) in C. elegans). Each stage of nematode larval development is characterized by proliferation of specific cell lineages and an increase in body size without alteration of the basic body plan. Nematode larval stages are separated by molts in which each stage-specific exoskeleton, or cuticle, is shed and replaced anew.
1 O76840 (/IMP)
Transforming growth factor beta receptor signaling pathway GO:0007179
A series of molecular signals initiated by the binding of an extracellular ligand to a transforming growth factor beta receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.
1 Q7TQN3 (/IDA)
Transforming growth factor beta receptor signaling pathway GO:0007179
A series of molecular signals initiated by the binding of an extracellular ligand to a transforming growth factor beta receptor on the surface of a target cell, and ending with regulation of a downstream cellular process, e.g. transcription.
1 Q8TEU8 (/ISS)
Embryo development ending in birth or egg hatching GO:0009792
The process whose specific outcome is the progression of an embryo over time, from zygote formation until the end of the embryonic life stage. The end of the embryonic life stage is organism-specific and may be somewhat arbitrary; for mammals it is usually considered to be birth, for insects the hatching of the first instar larva from the eggshell.
1 O76840 (/IMP)
Extracellular matrix organization GO:0030198
A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.
1 Q868Z9 (/IMP)
Multicellular organism reproduction GO:0032504
The biological process in which new individuals are produced by one or two multicellular organisms. The new individuals inherit some proportion of their genetic material from the parent or parents.
1 O76840 (/IMP)
Negative regulation of proteolysis GO:0045861
Any process that stops, prevents, or reduces the frequency, rate or extent of the hydrolysis of a peptide bond or bonds within a protein.
1 Q8R0S6 (/ISO)
Embryonic morphogenesis GO:0048598
The process in which anatomical structures are generated and organized during the embryonic phase. The embryonic phase begins with zygote formation. The end of the embryonic phase is organism-specific. For example, it would be at birth for mammals, larval hatching for insects and seed dormancy in plants.
