Summary: This gene generates several transcript variants which differ in their first exons. At least three alternatively spliced variants encoding distinct proteins have been reported, two of which encode structurally related isoforms known to function as inhibitors of CDK4 kinase. The remaining transcript includes an alternate first exon located 20 Kb upstream of the remainder of the gene; this transcript contains an alternate open reading frame (ARF) that specifies a protein which is structurally unrelated to the products of the other variants. This ARF product functions as a stabilizer of the tumor suppressor protein p53 as it can interact with, and sequester, the E3 ubiquitin-protein ligase MDM2, a protein responsible for the degradation of p53. In spite of the structural and functional differences, the CDK inhibitor isoforms and the ARF product encoded by this gene, through the regulatory roles of CDK4 and p53 in cell cycle G1 progression, share a common functionality in cell cycle G1 control. This gene is frequently mutated or deleted in a wide variety of tumors, and is known to be an important tumor suppressor gene. [provided by RefSeq, Sep 2012]

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.

See identical proteins and their annotated locations for NP_000068.1

Status: REVIEWED

Description

Transcript Variant: This variant (1) is also known as alpha. Transcripts 1 and 4, encoding p16INK4a and p14ARF, have distinct first exons which contain the translation start codon, and share a common second exon, which is translated in different reading frames. Thus, the p16INK4a protein encoded by this variant (1) lacks sequence similarity to the protein product of variant 4 (p14ARF).

Status: REVIEWED

Description

Transcript Variant: This variant (5) includes an additional exon that causes a frameshift in the 3' coding region, compared to variant 1 (encoding p16INK4a). The resulting isoform (p16gamma) has a distinct C-terminus and is longer than p16INK4a. This variant has been described in PMID:17486064. It is a candidate for nonsense-mediated mRNA decay (NMD), but it is not known if the endogenous protein is expressed in vivo.

Status: REVIEWED

Description

Transcript Variant: This variant (4), also known as beta, encodes p14ARF. Transcripts 1 and 4, encoding p16INK4a and p14ARF have distinct first exons which contain the translation start codon, and share a common second exon, which is translated in different reading frames. Thus, the p14ARF protein encoded by this variant (4) lacks sequence similarity to the protein product of variant 1 (p16INK4a). Note that this variant may use an alternative upstream start codon, which would produce an isoform that is 41 aa longer at the N-terminus, or an alternative downstream start codon, which would produce an isoform (smARF, described in PMID:16713577) that is 47 aa shorter at the N-terminus; it is unclear if the isoforms derived from the alternative start codons are present in vivo. The p14ARF protein is known to be nucleoplasmic but may also be recruited to mitochondria, as described in PMID:20107316.

Description

Transcript Variant: This variant (3) contains an alternate open reading frame (ARF), when compared to variants 1 or 4. The ARF results from an alternative splicing between a distinct first exon, which contains the translation start codon, and the common second exon. Thus, the protein encoded by this variant (p12) lacks sequence similarity to the protein product of variant 4. This variant is specifically expressed in pancreas, and has been described in PMID:10445844. It is a candidate for nonsense-mediated mRNA decay (NMD), but it is not known if the endogenous protein is expressed in vivo.
