Summary: Predicted to enable phosphatidylinositol 3-kinase binding activity; transmembrane receptor protein tyrosine kinase activity; and virus receptor activity. Involved in several processes, including platelet aggregation; positive regulation of phosphatidylinositol 3-kinase/protein kinase B signal transduction; and regulation of defense response. Acts upstream of or within several processes, including nervous system development; substrate adhesion-dependent cell spreading; and vagina development. Predicted to be located in cell surface; endoplasmic reticulum membrane; and nuclear envelope. Predicted to be part of receptor complex. Predicted to be active in plasma membrane. Is expressed in several structures, including brain; genitourinary system; gut; limb; and sensory organ. Used to study autoimmune disease. Orthologous to human TYRO3 (TYRO3 protein tyrosine kinase).

Loss of the Tyro3 receptor correlates with significantly thinner myelin sheaths in both unchallenged mice and during remyelination, particularly in larger caliber axons. Primary effect of Tyro3 is upon the radial expansion of myelin. The loss of Tyro3 leads to a reduction in the number of myelin lamellae on axons.
Title: The TAM receptor TYRO3 is a critical regulator of myelin thickness in the central nervous system.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

mRNA and Protein(s)

NM_001290800.2 → NP_001277729.1 tyrosine-protein kinase receptor TYRO3 isoform B

Status: VALIDATED

Description

Transcript Variant: This variant (2) contains alternative 5' exon structure, and it thus differs in its 5' UTR and initiates translation from an alternative start codon, compared to variant 1. The encoded isoform (B) has a distinct N-terminus and is shorter than isoform A.
