MAP6 is present at the Golgi complex and in secretory vesicles in unpolarized cells and re-distributed to newly forming axons, where it binds and stabilizes axonal microtubules. A palmitoylation cycle controls MAP6 membrane-microtubule shuttling and is required for its polarized distribution in axons.

MAP6 deletion disrupts brain connectivity and is associated with a lack of post-commissural fornix fibres. MAP6 contributes to fornix development by regulating axonal elongation induced by Semaphorin 3E.

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_001043355.2 → NP_001036820.2 microtubule-associated protein 6 isoform 3

Status: VALIDATED

Description

Transcript Variant: This variant (3) differs in the 5' coding region, uses a downstream, in-frame start codon as described in PubMed: 14567673, and lacks an alternate exon in the 3' coding region that results in a frameshift, compared to variant 1. These differences result in a shorter protein (isoform 3, also known as F-STOP) with shorter and distinct N- and C-termini, compared to isoform 1.
