Stra6 function
What you want to ask is what is the function of stra6? Stra6 has the function of transporting proteins. Zhong Ming of Southeast University Medical College wrote in the latest research results published by PNAS that stra6 is not only a receptor of RBP, but also a transporter, which can mediate RBP to release vitamin A and transport it across cell membrane. So stra6 acts as a transporter.
