TYRO protein tyrosine kinase-binding protein is an adapter protein that in humans is encoded by the TYROBP gene.[5][6]

Function

[edit]

This gene encodes a transmembrane signaling polypeptide which contains an immunoreceptor tyrosine-based activation motif (ITAM) in its cytoplasmic domain. The encoded protein may associate with the killer cell immunoglobulin-like receptor (KIR) family of membrane glycoproteins and may act as an activating signal transduction element. This protein may bind zeta-chain associated protein kinase 70 kDa (ZAP-70) and spleen tyrosine kinase (SYK) and play a role in signal transduction, bone modeling, brain myelination, and inflammation. Mutations within this gene have been associated with polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy (PLOSL), also known as Nasu-Hakola disease. Its putative receptor, triggering receptor expressed on myeloid cells 2 (TREM2), also causes PLOSL. Two alternative transcript variants encoding distinct isoforms have been identified for this gene. Other alternative splice variants have been described, but their full-length nature has not been determined.[7]

Interactions

[edit]

TYROBP has been shown to interact with SIRPB1.[8][9]

Clinical significance

[edit]

Pathological mutations of the TYROBP gene cause polycystic lipomembranous osteodysplasia with sclerosing leukoencephalopathy 1, a condition presenting as early-onset dementia.
