Function
Participates in at least several B-cell activation processes as well as of other cell types. It is a costimulator of DNA-synthesis. It induces the expression of class II MHC molecules on resting B-cells. It enhances both secretion and cell surface expression of IgE and IgG1. It also regulates the expression of the low affinity Fc receptor for IgE (CD23) on both lymphocytes and monocytes. -
Involvement in disease
Genetic variations in IL4 may be a cause of susceptibility to ischemic stroke (ISCHSTR) [MIM:601367]; also known as cerebrovascular accident or cerebral infarction. A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors. -

Belongs to the IL-4/IL-13 family. -

Images
-
Densitometry of protein isoforms visualised by 2-DE. The triangle indicates the theoretical MW and pI of the protein.
-
1D SDS-PAGE of ab83686 before and after treatment with glycosidases to remove oligosaccharides. A drop in the observed MW after treatment indicates the presence of glycosylation.
Lane 1: ab83686
Lane 2: ab83686 treated with PNGase F to remove potential N-linked glycans
Lane 3: ab83686 treated with a glycosidase cocktail to remove potential N- and O-linked glycans. 10 μg protein loaded per lane; Deep Purple™ stained.
Additional bands in lane 2 and lane 3 are glycosidase enzymes.
