The ABCB19 protein looks like a V-shaped clip with two openings. It is a small "tunnel" swimming on the cell membrane. In the future, further functional analysis and transformation of this family of proteins will provide more help for people to understand and utilize Brassinosteroid signaling to promote agricultural production.
