FunFam 79401: Plexin A1

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 4 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
Receptor activity GO:0004872
Combining with an extracellular or intracellular messenger to initiate a change in cell activity.
1 Q9UIW2 (/TAS)
Protein binding GO:0005515
Interacting selectively and non-covalently with any protein or protein complex (a complex of two or more proteins that may include other nonprotein molecules).
1 P70206 (/IPI)
Semaphorin receptor activity GO:0017154
Combining with a semaphorin, and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.
1 P70206 (/IPI)
Semaphorin receptor activity GO:0017154
Combining with a semaphorin, and transmitting the signal from one side of the membrane to the other to initiate a change in cell activity.
1 Q9UIW2 (/TAS)

There are 5 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
Multicellular organism development GO:0007275
The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).
1 Q9UIW2 (/TAS)
Regulation of smooth muscle cell migration GO:0014910
Any process that modulates the frequency, rate or extent of smooth muscle cell migration.
1 P70206 (/IMP)
Dichotomous subdivision of terminal units involved in salivary gland branching GO:0060666
The process in which a salivary epithelial cord bifurcates at its end.
1 P70206 (/IDA)
Neuron projection guidance GO:0097485
The process in which the migration of a neuron projection is directed to a specific target site in response to a combination of attractive and repulsive cues.
1 P70206 (/IMP)
Neuron projection extension GO:1990138
Long distance growth of a single neuron projection involved in cellular development. A neuron projection is a prolongation or process extending from a nerve cell, e.g. an axon or dendrite.
1 P70206 (/IGI)

There are 5 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
Plasma membrane GO:0005886
The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.
2 P70206 (/TAS) Q9UIW2 (/TAS)
Semaphorin receptor complex GO:0002116
A stable binary complex of a neurophilin and a plexin, together forming a functional semaphorin receptor.
1 Q9UIW2 (/TAS)
Membrane GO:0016020
A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
1 P70206 (/IDA)
Extracellular exosome GO:0070062
A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
1 Q9UIW2 (/IDA)
Extracellular exosome GO:0070062
A vesicle that is released into the extracellular region by fusion of the limiting endosomal membrane of a multivesicular body with the plasma membrane. Extracellular exosomes, also simply called exosomes, have a diameter of about 40-100 nm.
