This article is about the cell adhesion molecule. For NRT 1.1, a dual-affinity plant nitrate transporter formally known as CHL1[5], see major facilitator superfamily.

CHL1 is a cell adhesion molecule closely related to the L1. In melanocytic cells CHL1 gene expression may be regulated by MITF,[7] and can act as a helicase protein during the interphase stage of mitosis.

The protein, however, has dynamic localisation, meaning that it has not only multiple roles in the cell, but also various locations.
