Target intelligence / Profile preview

Mannosidase, alpha, class 1B, member 1 pseudogene (MAN1B1 pseudogene (no universally accepted abbreviation; MAN1B1 is used for the functional gene))

Target: MAN1B1 pseudogene (no universally accepted abbreviation; MAN1B1 is used for the functional gene)
Molecular classification: Pseudogene, Processed pseudogene (most pseudogenes of this type arise from reverse transcription of mRNA and reintegration into the genome, losing function)

Overview

This target is a **pseudogene** corresponding to the protein coding gene *mannosidase alpha class 1B member 1* (MAN1B1). Pseudogenes are genomic sequences similar to known genes that have lost their ability to encode a functional protein, mostly due to mutations or lack of regulatory elements[4][2]. The MAN1B1 *protein coding* gene is an enzyme involved in N-glycan biosynthesis and ER protein quality control, whose mutations can cause certain congenital diseases[1][3]. However, the ENSG00000254725 entry is for a related pseudogene — it is not transcribed or translated into a functional enzyme and has no therapeutic or biological relevance as a target[5][4].

Other names: MAN1B1 pseudogeneMannosidase, alpha, class 1B, member 1 pseudogene

Mechanism of action

None (as above, no active protein product, thus no mechanism of action for drugs)

Biological functions

No direct biological function (pseudogenes are generally nonfunctional DNA sequences that resemble functional genes but cannot produce active proteins)

Disease associations

None directly for the pseudogene itself; functional MAN1B1 gene mutations are associated with congenital disorders of glycosylation and Rafiq Syndrome, but pseudogene is not implicated

Safety considerations

None (no safety issues are relevant for pseudogenes; only possible confusion in genetic studies and PCR bias due to high sequence similarity to functional genes)

Interacting drugs

None (no drugs interact with a pseudogene, as it does not encode a functional, druggable protein)

Biomarkers

None (pseudogenes are not used as biomarkers for patient selection or efficacy monitoring)
