Summaries for MKKS Gene

Entrez Gene Summary for MKKS Gene

  • This gene encodes a protein which shares sequence similarity with other members of the type II chaperonin family. The encoded protein is a centrosome-shuttling protein and plays an important role in cytokinesis. This protein also interacts with other type II chaperonin members to form a complex known as the BBSome, which involves ciliary membrane biogenesis. This protein is encoded by a downstream open reading frame (dORF). Several upstream open reading frames (uORFs) have been identified, which repress the translation of the dORF, and two of which can encode small mitochondrial membrane proteins. Mutations in this gene have been observed in patients with Bardet-Biedl syndrome type 6, also known as McKusick-Kaufman syndrome. Alternative splicing results in multiple transcript variants.

GeneCards Summary for MKKS Gene

MKKS (McKusick-Kaufman Syndrome) is a Protein Coding gene. Diseases associated with MKKS include Mckusick-Kaufman Syndrome and Bardet-Biedl Syndrome 6. Among its related pathways are Organelle biogenesis and maintenance and Cargo trafficking to the periciliary membrane. Gene Ontology (GO) annotations related to this gene include unfolded protein binding and RNA polymerase II repressing transcription factor binding.

UniProtKB/Swiss-Prot for MKKS Gene

  • Probable molecular chaperone. Assists the folding of proteins upon ATP hydrolysis. As part of the BBS/CCT complex plays a role in the assembly of BBSome, a complex involved in ciliogenesis regulating transports vesicles to the cilia. May play a role in protein processing in limb, cardiac and reproductive system development. May play a role in cytokinesis.

Cytoplasm, cytoskeleton, microtubule organizing center, centrosome. Cytoplasm, cytosol. Nucleus. Note=The majority of the protein resides within the pericentriolar material (PCM), a proteinaceous tube surrounding centrioles. During interphase, the protein is confined to the lateral surfaces of the PCM but during mitosis it relocalizes throughout the PCM and is found at the intercellular bridge. The MKSS protein is highly mobile and rapidly shuttles between the cytosol and centrosome.
