FunFam 106: Potassium channel subfamily K member 4

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 11 GO terms relating to "molecular function"

Sensory perception of pain GO:0019233
The series of events required for an organism to receive a painful stimulus, convert it to a molecular signal, and recognize and characterize the signal.

Pain may come from extremes of temperature, mechanical damage, electricity or from noxious chemical substances. This is a neurological process.
