LTK is a glycoprotein member of the tyrosine protein kinase family, insulin receptor subfamily of proteins.
There are multiple isoforms that run between 50 and 100kD in SDS-Page.
It is reportedly expressed in lymphocytes and cerebral cortex neurons, plus cardiomyocytes where it plays a role in cellular hypertrophy.
Mature human LTK is an 848aa type I transmembrane protein that is embedded in the ER.
It contains a 408aa extracellular domain aa17-424 plus a 415aa cytoplasmic region aa450-864.
The cytoplasmic region possesses multiple phosphotyrosines that interact with downstream signaling molecules.
There is also a protein kinase domain between aa510-786.
LTK apparently undergoes dimer- and trimerization under certain circumstances.
There are multiple splice variants for LTK.
Two isoforms possess a common deletion of aa274-334 that may be accompanied by a 27aa substitution for aa449-544.
Another isoform shows an alternative start site at aa406 accompanied by a 17aa substitution for aa449, while a fourth isoform contains a 51aa substitution for aa171-864.
A final 50kD isoform shows a 28aa substitution for aa449-864.
Over aa17-424, human LTK shares 75% aa identity with mouse LTK.
