Summary: Involved in myoblast fusion; plasma membrane fusion; and positive regulation of skeletal muscle hypertrophy. Acts upstream of or within myoblast fusion involved in skeletal muscle regeneration. Located in Golgi membrane and plasma membrane. Is expressed in several structures, including alimentary system; limb; skeletal musculature; and somite. Human ortholog(s) of this gene implicated in Carey-Fineman-Ziter syndrome. Orthologous to human MYMK (myomaker, myoblast fusion factor). [provided by Alliance of Genome Resources, Nov 2024]

Myocyte-derived Myomaker expression is required for regenerative fusion but exacerbates membrane instability in dystrophic myofibers.
Title: Myocyte-derived Myomaker expression is required for regenerative fusion but exacerbates membrane instability in dystrophic myofibers.
the Myomixer-Myomaker pair controls the critical step in myofiber formation during muscle development.
Title: Control of muscle formation by the fusogenic micropeptide myomixer.
These data reveal that myoblast fusion requires myomaker activity at the plasma membrane and is potentially regulated by proper myomaker trafficking.
Title: Insights into the localization and function of myomaker during myoblast fusion.
This study indicated that myomaker could be used in nonmuscle cells to induce fusion with muscle in vivo, thereby providing a platform to deliver therapeutic material.
Title: In vivo myomaker-mediated heterologous fusion and nuclear reprogramming.
Functional studies showed that miR-491 overexpression suppressed muscle cell differentiation and adult muscle regeneration, while the inhibition of miR-491 promoted myotube differentiation. Taken together, the findings identified miR-491 as a novel negative regulator of myogenic differentiation through targeting myomaker.
Title: miR-491 inhibits skeletal muscle differentiation through targeting myomaker.
data indicate that the majority of myomaker is embedded in the plasma membrane with seven membrane-spanning regions and a required intracellular C-terminal tail.
Title: Structure-function analysis of myomaker domains required for myoblast fusion.
myogenic basic helix-loop-helix (bHLH) transcription factors induce myomaker expression in satellite cells during acute and chronic muscle regeneration.
Title: Myomaker is essential for muscle regeneration.
The findings reveal myomaker (transmembrane protein 8c) as a long-sought myogenic fusion protein that controls mammalian myoblast fusion.
Title: Myomaker is a membrane activator of myoblast fusion and muscle formation.

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.
