| Functional | "Acid-sensing ion channel (ASIC) 4 promotes the degradation of ASIC1 or inhibits its expression." | 10.3390/ani12243571 |
| Mutation Description | "(...) ASCI4 was identified to be pseudogenized in all toothed whales except the sperm whale due to premature stop codons detected in the first exon of the sequences (Figures 1 and S1)." | 10.3390/ani12243571 |
| Phenotypic | "ASIC1 is the most abundant proton-gated ion channel gene in mammals. It is involved in the transmission of pain signals, and its degradation or reduced expression can lead to insensitivity to pain [64]. Therefore, the relaxed selection (and pseudogenization) of ASIC4 in toothed whales may have deprived it of its inhibitory effect on ASIC1, thereby making toothed whales more sensitive to pain." | 10.3390/ani12243571 |
Curator Observations
Shared premature stop codon in exon1 indicates a ancestral loss in Odontoceti with the exception of sperm whales.
