Scientific Data Images for Human SOS2 Antibody
Detection of Human SOS2 by Western Blot.
Western blot shows lysates of K562 human chronic myelogenous leukemia cell line and 293T human embryonic kidney cell line. PVDF Membrane was probed with 2 µg/mL of Goat Anti-Human SOS2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF6260) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for SOS2 at approximately 160 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.Applications for Human SOS2 Antibody

Background: SOS2
SOS2 (Son of sevenless homolog 2) is a 160‑170 kDa protein that regulates Ras signaling. It is widely expressed, and serves as a mediator of guanine nucleotide phosphate exchange. In the resting cell, cytoplasmic SOS2 forms a heterodimer with Grb2, and a heterotrimer with Eps8 and E3b1. Upon RTK activation, the SOS heterodimer is recruited to the cell membrane, where it contacts GDP‑bound Ras. This allows it to facilitate a GTP‑for‑GDP exchange that activates Ras. The heterotrimer interacts with Rac on actin filaments. SOS2 activity parallels that of SOS1. Relative to SOS1, however, SOS2 binds Grb2 with higher affinity and shows less biological activity due to a shorter half‑life. Human SOS2 is 1332 amino acids (aa) in length and contains one histone fold (aa 97‑169), PH (aa 439‑546) and REM (aa 595‑739) domains that interact with Ras, and a Pro‑rich region that binds to Grb2 (aa 1126‑1242).
