LMAN1
Domain
The FF ER export motif at the C-terminus is not sufficient to support endoplasmic reticulum exit, and needs assistance of Gln-501 for proper recognition of COPII coat components.
Function
Mannose-specific lectin. May recognize sugar residues of glycoproteins, glycolipids, or glycosylphosphatidyl inositol anchors and may be involved in the sorting or recycling of proteins, lipids, or both. The LMAN1-MCFD2 complex forms a specific cargo receptor for the ER-to-Golgi transport of selected proteins.
Involvement in disease
Factor V and factor VIII combined deficiency 1
F5F8D1
A blood coagulation disorder characterized by bleeding symptoms similar to those in hemophilia or parahemophilia, that are caused by single deficiency of FV or FVIII, respectively. The most common symptoms are epistaxis, menorrhagia, and excessive bleeding during or after trauma. Plasma levels of coagulation factors V and VIII are in the range of 5 to 30% of normal.
None
The disease is caused by variants affecting the gene represented in this entry.
Post-translational modifications
The N-terminal may be partly blocked.
Tissue Specificity
Ubiquitous.
