General description

Sox-1 protein (SOX1), also known as SRY (Sex determining region Y)-box 1, is expressed in the developing brain. SOX1 is related to the HMG box of family transcription factors, which are a highly motile group, with a highly conserved DNA binding domain. Sox1 utilizes multiple pathways to play a direct role on cell fate. SOX1 is also directly involved with sex determination of the Y chromosome. Binding of the SOX1, C-terminus, to the Hes 1 promoter results in Hes1 suppression and attenuation of Notch signaling. When the C-terminus of SOX1 binds to β-catenin, TCF/LEF is suppressed, resulting in the attenuation of Wnt signaling. SOX1, therefore, defines the dividing neural precursors of the embryonic central nervous system.


This antibody recognizes SOX1 near the N-terminus.


Epitope: Near N-terminus

KLH-conjugated linear peptide corresponding to human SOX1 near the N-terminus.
