TULP3 is recruited to the primary cilium through a direct interaction with the retrograde transport IFT-A complex and with membrane phosphoinositides (Santagata et al, 2001; Mukhopadhyay et al, 2010; Qin et al, 2011; reviewed in Mukhopadhyay and Rohatgi, 2014). TULP3 facilitates GLI processing by recruiting the GPCR GPR161, which in turn activates PKA by increasing cAMP levels in a G alpha s-dependent manner (Mukhopadhyay et al, 2013, reviewed in Hwang and Mukhopadhyay, 2014; Pal and Mukhopadhyay, 2014).
