[https://www.uniprot.org/uniprot/LTOR2_MOUSE LTOR2_MOUSE] As part of the Ragulator complex it is involved in amino acid sensing and activation of mTORC1, a signaling complex promoting cell growth in response to growth factors, energy levels, and amino acids. Activated by amino acids through a mechanism involving the lysosomal V-ATPase, the Ragulator functions as a guanine nucleotide exchange factor activating the small GTPases Rag. Activated Ragulator and Rag GTPases function as a scaffold recruiting mTORC1 to lysosomes where it is in turn activated. Adapter protein that enhances the efficiency of the MAP kinase cascade facilitating the activation of MAPK2.<ref>PMID:15263099</ref>

The adaptor protein p14 is associated with the cytoplasmic face of late endosomes that is involved in cell-surface receptor endocytosis and it also directly interacts with MP1, a scaffolding protein that binds the MAP kinase ERK1 and its upstream kinase activator MEK1. The interaction of p14 with MP1 recruits the latter to late endosomes and the endosomal localization of p14/MP1-MEK1-ERK1 scaffolding complex is required for signaling via ERK MAP kinase in an efficient and specific manner upon receptor stimulation. Here, we report the three-dimensional solution structure of the adaptor protein p14. The structure reveals a profilin-like fold with a central five-stranded beta-sheet sandwiched between alpha-helices. Unlike profilin, however, p14 exhibits weak interaction with selective phosphoinositides but no affinity towards proline-rich sequences. Structural comparison between profilin and p14 reveals the molecular basis for the differences in these functions. We further mapped the MP1 binding sites on p14 by NMR, and discuss the implications of these important findings on the possible function of p14.
