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

Function
LAMP3 · Lysosome associated membrane protein 3
This gene encodes lysosome-associated membrane glycoprotein 3, a type 1 integral membrane protein that belongs to a family of lysosome associated membrane proteins which form part of the glycoconjugate coat present on the inside of the lysosomal membrane. It is predominantly expressed in mature dendritic cells and serves as a marker of dendritic cell maturation. The encoded protein localizes primarily to late endosomes/lysosomes and the MHC class II compartment, where it contributes to antigen processing and presentation during adaptive immune responses. The expression of this gene is inducible under hypoxic conditions via hypoxia-inducible factor 1-alpha signaling. In cancer, this gene is frequently overexpressed and is associated with tumor progression, metastasis, therapy resistance, and poor clinical prognosis in multiple malignancies including breast, cervical, and ovarian cancers.

Isoforms & Proteins
2 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
All 168 amino-acid changes on canonical ENST00000265598 · needle height = samples · drag the mini-map to zoom
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 frequency across cancer types
% of samples with a missense/complex mutation in LAMP3 · cell line vs tissue
For each cancer type, the fraction of samples that carry at least one missense/complex mutation anywhere in LAMP3 – counted as distinct samples (a sample counts once no matter how many mutations it has).
Split into cell line and tissue; each cell shows mutated / total and the percentage. Cohorts with <20 samples are omitted. Ordered by combined frequency.
