FunFam 68: SPARC isoform 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 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.

Receptor-mediated endocytosis GO:0006898
An endocytosis process in which cell surface receptors ensure specificity of transport.

Receptor-mediated endocytosis generally occurs via clathrin-coated pits and vesicles.

Glutamatergic synapse GO:0098978
A synapse that uses glutamate as a neurotransmitter.
2 P16975 (/EXP) P24054 (/EXP)
Nucleus GO:0005634
A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

Vesicle GO:0031982
Any small, fluid-filled, spherical organelle enclosed by membrane.
1 P16975 (/IDA)
Synapse GO:0045202
The junction between a nerve fiber of one neuron and another neuron, muscle fiber or glial cell. As the nerve fiber approaches the synapse it enlarges into a specialized structure, the presynaptic nerve ending, which contains mitochondria and synaptic vesicles. At the tip of the nerve ending is the presynaptic membrane; facing it, and separated from it by a minute cleft (the synaptic cleft) is a specialized area of membrane on the receiving cell, known as the postsynaptic membrane. In response to the arrival of nerve impulses, the presynaptic nerve ending secretes molecules of neurotransmitters into the synaptic cleft. These diffuse across the cleft and transmit the signal to the postsynaptic membrane.

Extracellular matrix of synaptic cleft GO:0098965
The portion of the extracellular matrix that lies within the synaptic cleft.

Extracellular matrix of synaptic cleft GO:0098965
The portion of the extracellular matrix that lies within the synaptic cleft.

Glutamatergic synapse GO:0098978
A synapse that uses glutamate as a neurotransmitter.
