It is unclear whether SHP1 directly dephosphorylates KIT or elicits dephosphorylation of the receptor indirectly by dephosphorylating and inhibiting cytosolic PTKs that act on KIT. SHP-1 may also compete with and displace SFKs or other proteins that dock to phosphorylated Y570 (Kozlowski et al, 1998). SHP-1:p-c-Kit complex
