Findings demonstrate that GPM6B plays a crucial role in SMC differentiation and regulates SMC differentiation through the activation of TGF-beta-Smad2/3 signaling via direct interactions with TbetaRI.
Title: Glycoprotein M6B Interacts with TβRI to Activate TGF-β-Smad2/3 Signaling and Promote Smooth Muscle Cell Differentiation.
Study identified glycoprotein M6B as a Schwann cell microvilli component of peripheral nodes of Ranvier. Study detected Na(+) channel clusters at heminodes without any associated M6B, indicating that it is not required for initial channel clustering; showed that absence of M6B results in progressive appearance of nodal protrusions of the nodal axolemma, that are often accompanied by the presence of enlarged mitochondria.
Title: Glial M6B stabilizes the axonal membrane at peripheral nodes of Ranvier.
The results of this study proposed that M6b proteins are required for proper extension and guidance of callosal axons that follow one of the most complex trajectories in the mammalian nervous system.

M6B is not efficiently sorted into mature myelin, in which it is 200-fold less abundant than proteolipid protein (PLP).

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.
