About LAMTOR3

Cytogenetic location: 4q23 Genomic coordinates (GRCh38): 4:99,878,336-99,894,546 (from NCBI)

This gene has 3 transcripts (splice variants) and 220 orthologues. Ubiquitous expression in thyroid (RPKM 13.3), brain (RPKM 11.2) and 25 other tissues.

Summary

This gene encodes a scaffold protein that functions in the extracellular signal-regulated kinase (ERK) cascade. The protein is localized to late endosomes by the mitogen-activated protein-binding protein-interacting protein, and binds specifically to MAP kinase kinase MAP2K1/MEK1, MAP kinase MAPK3/ERK1, and MAP kinase MAPK1/ERK2. Studies of the orthologous gene in mouse indicate that it regulates late endosomal traffic and cell proliferation. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. A pseudogene of this gene is located on the long arm of chromosome 13.
