Table 2 Gene ontology classification of PTC genes.

From: Genome-wide analysis of chimpanzee genes with premature termination codons

Ontology

Overrepresented GO term in the PTC dataset

Number of PTC genes in the GO category*

Adjusted p-value

Molecular function

Olfactory receptor activity (GO:0004984)

46

1*10-6

Biological process

Sensory perception of smell (GO:0007608)

46

3*10-7

Biological process

G-protein coupled receptor protein signaling pathway (GO:0007186)

82

2*10-5

  1. * Note that the GO terms overlap. The two groups olfactory receptor activity and sensory perception of smell are identical and these 46 genes are in turn included in the group G-protein coupled receptor activity.
