== Disease ==

[https://www.uniprot.org/uniprot/MA1B1_HUMAN MA1B1_HUMAN] Defects in MAN1B1 are the cause of mental retardation autosomal recessive type 15 (MRT15) [MIM:[https://omim.org/entry/614202 614202]. Mental retardation is characterized by significantly below average general intellectual functioning associated with impairments in adaptative behavior and manifested during the developmental period.<ref>PMID:21763484</ref>

== Function ==
 +
[https://www.uniprot.org/uniprot/MA1B1_HUMAN MA1B1_HUMAN] Involved in glycoprotein quality control targeting of misfolded glycoproteins for degradation. It primarily trims a single alpha-1,2-linked mannose residue from Man(9)GlcNAc(2) to produce Man(8)GlcNAc(2), but at high enzyme concentrations, as found in the ER quality control compartment (ERQC), it further trims the carbohydrates to Man(5-6)GlcNAc(2).<ref>PMID:12090241</ref> <ref>PMID:18003979</ref>
