Also known as: PAM18; TIM14; TIMM14
Summary: The protein encoded by this gene is thought to be part of a complex involved in the ATP-dependent transport of transit peptide-containing proteins from the inner cell membrane to the mitochondrial matrix. Defects in this gene are a cause of 3-methylglutaconic aciduria type 5 (MGA5), also known as dilated cardiomyopathy with ataxia (DCMA). Alternative splicing of this gene results in multiple transcript variants. Related pseudogenes have been identified on chromosomes 1, 2, 6, 10, 14 and 19. [provided by RefSeq, Jan 2012]

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.

NR_033721.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (3) lacks an alternate exon in the 5' region, compared to variant 1. This variant is represented as non-coding due to the presence of an upstream ORF that is predicted to interfere with translation of the longest in-frame ORF, as found in variant 2.

NR_033722.2 RNA Sequence

Status: REVIEWED

Description

Transcript Variant: This variant (4) lacks an alternate exon in the central region, 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).
