Human anti GEP100 antibody recognizes IQ motif and SEC7 domain-containing protein 1, also known as ARFGEP100 and BRAG2.

GEP100 is a guanine nucleotide exchange factor for ARF6, a component of the RAS superfamily involved with membrane trafficking (You et al. 2019). AMAP1 is then the downstream effector of activated ARF6 (Kinoshita et al. 2013). GEP100 appears to control oncogenic processes in response to stimulation of EGF (Hu et al. 2013), also interacting specifically with EGF R (Hu et al. 2012). For example, in breast cancer, activation of ARF6 through GEP100 leads to invasion and metastasis through the EGF R pathway. GEP100 overexpression alongside ARF6 can also cause noninvasive MCF7 cells to become invasive (Sabe et al. 2009).
