Stats by Source
Global, split by cell line (COSMIC CL / DepMap / PubMed) vs tissue (COSMIC primary tissue)
Global = all mutations for this gene across every source.
Cell line = COSMIC Cell Lines Project + DepMap + PubMed.
Tissue = COSMIC primary-tissue (patient tumour) samples.
Global can exceed cell line + tissue: COSMIC tissue-derived models sit only in global, and a peptide can be shared across both.

Function
GATD3A · Glutamine amidotransferase-like class 1 domain-containing protein 3, mitochondrial
Acts as a mitochondrial deglycase involved in the removal of early non-enzymatic glycation adducts from amino acids and nucleotides, thereby restricting the formation of advanced glycation end products (AGEs) within mitochondria (PubMed:35307029). Required to maintain low levels of glycation on mitochondrial ribosomal RNA and proteins, supporting efficient mitochondrial gene expression. Contributes to mitochondrial homeostasis, normal respiratory capacity, and proper mitochondrial network organization. Acts also as a mitochondrial regulator of malate dehydrogenase MDH2 by competitively limiting the association of MDH2 with the mitochondrial deacetylase SIRT3, thereby preserving MDH2 acetylation and enzymatic activity. Through this mechanism, supports efficient conversion of malate to oxaloacetate, sustaining TCA cycle continuity and oxidative phosphorylation (PubMed:39738099)
Isoforms & Proteins
4 transcripts · UniProt mapping is sequence-verified (AA-safe)
Each Ensembl transcript (ENST) this gene is mutated on, with its matched UniProt accession.
The mapping is sequence-verified: the UniProt sequence is identical to the transcript translation, so amino-acid positions line up exactly. A * marks an unreviewed (TrEMBL) entry.
Counts are mutations and unique mutant peptides on each transcript.

Gene Properties
Recurrent Mutations
Top recurrent amino-acid changes along the protein · needle height = number of mutations
A lollipop / needle plot – the standard way to show recurrent mutations along a protein (as used by cBioPortal and MutationMapper).
X-axis = amino-acid position in the protein.
Needle height & head size = how often that exact amino-acid change was observed (its recurrence). Tall/large heads are mutational hotspots.
The most recurrent changes are labelled; hover any needle for the change, position and counts.
Mutation Distribution
Where GATD3A is mutated · all tissues, split by cell line vs tissue
How many mutations in GATD3A were found in each tissue, across the whole database.
Each bar is a tissue (cell-line and tissue names are merged to the standard tissue), split into cell line and tissue (patient tumour) contributions.
This shows the cancer-context where this gene is recurrently altered.
