Summaries for FAM20A Gene

Entrez Gene Summary for FAM20A Gene

  • This locus encodes a protein that is likely secreted and may function in hematopoiesis. A mutation at this locus has been associated with amelogenesis imperfecta and gingival hyperplasia syndrome. Alternatively spliced transcript variants have been identified. [provided by RefSeq, Aug 2011]

GeneCards Summary for FAM20A Gene

FAM20A (FAM20A, Golgi Associated Secretory Pathway Pseudokinase) is a Protein Coding gene. Diseases associated with FAM20A include Amelogenesis Imperfecta, Type Ig and Amelogenesis Imperfecta-Gingival Hyperplasia Syndrome. An important paralog of this gene is FAM20C.

UniProtKB/Swiss-Prot for FAM20A Gene

  • Pseudokinase that acts as an allosteric activator of the Golgi serine/threonine protein kinase FAM20C and is involved in biomineralization of teeth. Forms a complex with FAM20C and increases the ability of FAM20C to phosphorylate the proteins that form the matrix that guides the deposition of the enamel minerals.
