Family with sequence similarity 133 member A (FAM133A)

Target
FAM133A
Molecular classification
Other (protein-coding gene; not a receptor, enzyme, transporter, channel, or transcription factor)
01

Overview

Family with sequence similarity 133 member A (FAM133A) is a protein-coding gene expressed in various tissues and implicated in diverse biological processes. It is involved in neuronal function (with evidence of regulation by catechol-O-methyltransferase genotype), shows significant correlations with cancer development and progression (notably in pancreatic adenocarcinoma and thyroid cancer), and has been suggested as a marker within immune response models in cervical cancer. Genetic association data further link FAM133A to metabolic traits such as fasting insulin levels, potentially intersecting with diabetes pathophysiology. Though FAM133A is associated with disease prognosis and biological regulation, it is not currently accepted as a classic druggable target (receptor, enzyme, etc.), and its direct molecular function remains to be fully elucidated

Mechanism of action

Not established. No drugs currently target FAM133A directly

03

Biological functions

Neuronal function regulation and possible modulation of estrogen‐responsive genesImplicated in cancer metastasis and tumorigenesis (co-expression network in pancreatic adenocarcinoma)Metabolic regulation connected with fasting insulin levelsPossible roles in immune microenvironment and biomarker potential for immune status in cancer
04

Disease associations

Cancer (implicated in pancreatic adenocarcinoma, papillary thyroid cancer, cervical cancer)Metabolic disease (association with fasting insulin regulation, suggesting a connection to type 2 diabetes pathophysiology)
05

Safety considerations

None known. No therapeutic interventions targeting FAM133A have been reported, therefore safety profile as a drug target is undetermined
06

Interacting drugs

None established. There are associations with gene expression changes after drug perturbation, but no direct evidence for drugs that interact specifically with FAM133A
07

Biomarkers

Potential biomarker in cancer, especially within immune gene–related prognostic models for cervical cancer and as a hub gene in pancreatic adenocarcinoma metastasis
