01

Overview

RPL35AP4 (Ribosomal protein L35a pseudogene 4) is a processed pseudogene in the human genome derived from the functional ribosomal protein L35a gene (RPL35A). Unlike its parent, RPL35AP4 does not encode a functional protein but may regulate gene expression through mechanisms similar to other pseudogenes, such as acting as a competitive endogenous RNA. Recent studies report that RPL35AP4 is highly expressed in glioma tissue, and its elevated levels are correlated with poorer prognosis and increased tumor malignancy. Functionally, silencing RPL35AP4 in glioma cell lines decreases proliferation, migration, and invasion capacities, and its expression is linked to immune cell infiltration in the glioma microenvironment. Therefore, RPL35AP4 may serve as a noncoding RNA biomarker for prognosis, particularly in glioma, but is not considered a standard therapeutic target. If you are seeking structured information for target/drug discovery or pharmacology, RPL35AP4 should be flagged as a non-target pseudogene biomarker candidate, not as a canonical target like a receptor or enzyme.

02

Mechanism of action

Not applicable. No drugs target this pseudogene or its function.

03

Biological functions

May have regulatory roles as a noncoding RNA in cancer, specifically glioma, regulating cell proliferation, invasion, and migrationNot involved in canonical ribosomal function (unlike its parent gene RPL35A)
04

Disease associations

Cancer (glioma, pan-cancer correlations in expression and prognosis)Other (possible associations with endocrine and immune dysfunction based on pseudogene family studies)
05

Biomarkers

RPL35AP4 has been proposed as a prognostic biomarker in glioma: high expression correlates with poor prognosis, malignant progression, immune infiltration (notably M2 macrophages), and specific molecular subtypes (IDH1 wild-type, 1p19q codeletion)
