ROR1 protein's minimal kinase activity in vitro suggests an improbable role as a tyrosine kinase in vivo. It serves as a receptor for WNT5A, activating NFkB signaling and potentially inhibiting WNT3A signaling. Notably, ROR1 plays a vital role in the inner ear, facilitating innervation of auditory hair cells by spiral ganglion neurons. ROR1 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived ROR1 protein, expressed by HEK293 , with C-Avi, C-6*His labeled tag.
