General annotation (Comments)

Function

Insulin-regulated facilitative glucose transporter.

Subunit structure

Binds to DAXX. Interacts via its N-terminus with SRFBP1. Ref.6 Ref.7

Subcellular location

Endomembrane system; Multi-pass membrane protein. Cytoplasmperinuclear region. Note: Localizes primarily to the perinuclear region, undergoing continued recycling to the plasma membrane where it is rapidly reinternalized. The dileucine internalization motif is critical for intracellular sequestration.

Tissue specificity

Skeletal and cardiac muscles; brown and white fat.

Post-translational modification

Sumoylated. Ref.6

Involvement in disease

Defects in SLC2A4 may be a cause of noninsulin-dependent diabetes mellitus (NIDDM) [MIM:125853]. Defects in SLC2A4 may be a cause of certain post-receptor defects in NIDDM. The variant in position Ile-383 is found in a small number of NIDDM patients, but seems not to be found in nondiabetic subjects. Ref.8 Ref.9 Ref.10

Miscellaneous

Insulin-stimulated phosphorylation of TBC1D4 is required for GLUT4 translocation By similarity.

Sequence similarities

Belongs to the major facilitator superfamily. Sugar transporter (TC 2.A.1.1) family. Glucose transporter subfamily. [View classification]
