General description

TBC1 domain family member 4 (TBC1D4) also known AS160, is a protein kinase B (Akt) substrate of 160 kDa. It is a Rab guanine triphosphatase (GTPase)-activating protein (GAP) protein. It consists of two phosphotyrosine-binding (PTB) domains at the N-terminal and a C-terminal catalytic Rab-GAP domain. This multi-domain protein also possesses Akt phosphorylation sites. The AS160 gene is mapped to human chromosome 13q22.2.


Anti-AS160 (C-terminal region) specifically recognizes human AS160.


Anti-AS160 (C-terminal region) antibody produced in rabbit may be used in immunoblotting and immunofluorescence.

Physical form

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.

Storage and Stability

Store at –20 °C. For continuous use, the product may be stored at 2–8 °C for up to one month. For extended storage, freeze in working aliquots at –20 °C. Repeated freezing and thawing is not recommended. Storage in “frost-free” freezers is also not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilutions should be discarded if not used within 12 hours.

Biochem/physiol Actions

AS160 protein mediates the translocation of glucose transporter 4 (GLUT4) storage vesicles to the plasma membrane (PM). It is a candidate signaling intermediate, identified as a functional link between the insulin signaling cascade and GLUT4 vesicles. AS160 is known to be phosphorylated by protein kinase B (Akt) on at least six separate sites in response to insulin and is thought to play an inhibitory role in the transport of GLUT4 vesicles. It is associated with GLUT4 vesicles in basal states and dissociates in response to insulin. The inhibitory role of AS160 in the basal state and reduced expression of AS160 in adipocytes has been shown to increase plasma membrane levels of GLUT4 in an insulin-dependent manner. Rab10 has been reported to be a target of AS160, required for insulin-stimulated translocation of GLUT4.
