Summary: This gene encodes a member of the acid-sensing ion channel (ASIC) family of proteins, which are part of the degenerin/epithelial sodium channel (DEG/ENaC) superfamily. Members of the ASIC family are sensitive to amiloride and function in neurotransmission. The encoded proteins function in learning, pain transduction, touch sensation, and development of memory and fear. Alternatively spliced transcript variants have been described.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

NM_001095.4 → NP_001086.2 acid-sensing ion channel 1 isoform b

See identical proteins and their annotated locations for NP_001086.2

Status: REVIEWED

Description

Transcript Variant: This variant (2) uses an alternate in-frame splice site in the 3' coding region, compared to variant 1. This results in a shorter protein (isoform b), compared to isoform a. Variants 2 and 6 both encode the same isoform (b).

Status: REVIEWED

Description

Transcript Variant: This variant (3) differs in the 5' UTR, lacks a portion of the 5' coding region, and initiates translation at an alternate start codon, compared to variant 1. This variant also uses an alternate, in-frame splice site in the 3' coding region compared to variant 1. The encoded isoform (c) has a distinct N-terminus and is shorter than isoform a.

RNA

NR_046389.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (4) contains an alternate internal exon and uses an alternate splice site, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
