B9D2 B9 domain containing 2 [Homo sapiens (human)] - Gene

Summary

Official Symbol: B9D2provided by HGNC
Official Full Name: B9 domain containing 2provided by HGNC
Primary source: HGNC:HGNC:28636
See related: Ensembl:ENSG00000123810 MIM:611951; AllianceGenome:HGNC:28636
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: MKS10; MKSR2; ICIS-1; JBTS34; MKSR-2
Summary: This gene encodes a B9 domain protein, which are exclusively found in ciliated organisms. The gene is upregulated during mucociliary differentiation, and the encoded protein localizes to basal bodies and cilia. Disrupting expression of this gene results in ciliogenesis defects.

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.
