Summary: Predicted to enable gap junction channel activity. Acts upstream of or within cell communication by electrical coupling and slow-twitch skeletal muscle fiber contraction. Predicted to be located in gap junction and plasma membrane. Predicted to be integral component of membrane. Predicted to be part of connexin complex. Is expressed in several structures, including eye; kidney; liver; musculature system; and spinal cord. [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Connexin 39.9 facilitates the spreading of neuronal inputs, which is irregular during motor development, beyond the muscle cells and that gap junctions play an essential role in the efficient recruitment of slow muscle fibers.

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.
