Species cross-reactivity is determined by western blot.

Applications Key: W=Western Blotting, IP=Immunoprecipitation,

Specificity / Sensitivity

SH3BP4 (D3D9I) Rabbit mAb recognizes endogenous levels of total SH3BP4 protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val222 of human SH3BP4 protein.

Western Blotting

Western Blotting

Western blot analysis of extracts from various cell lines using SH3BP4 (D3D9I) Rabbit mAb.



Immunoprecipitation of SH3BP4 from HeLa cell extracts. Lane 1 is 10% input, lane 2 is Rabbit (DA1E) mAb IgG XP® Isotype Control #3900, and lane 3 is SH3BP4 (D3D9I) Rabbit mAb. Western blot analysis was performed using SH3BP4 (D3D9I) Rabbit mAb.


The mTORC1 kinase complex is a critical regulator of cell growth (1,2). Its activity is modulated by enviromental factors such as energy levels, growth factors, and amino acids (3, 4). The GTPases RagA, RagB, RagC, and RagD mediate amino acid signaling to activate mTORC1 (1, 2). SH3BP4 (SH3 domain-binding protein 4) binds to the inactive Rag GTPase complex during amino acid starvation and prevents the association of Rag GTPase complex with mTORC1 resulting in the suppression of mTORC1 activation and cell growth (5).
