FAM83H

FAM83H is a is_associated_with::gene in humans that encodes a is_associated_with::protein known as FAM83H (uncharacterized protein FAM83H). FAM83H is targeted for the nucleus and it predicted to play a role in the structural development and calcification of tooth enamel.

Location


FAM83H is located on the long arm of is_associated_with::chromosome 8 (8q24.3), starting at 143723933 and ending at 143738030. The FAM83H gene spans 14097 base pairs and is orientated on the -- strand. The coding region is made up of 5,604 base pairs and 5 exons.

Expression


FAM83H is ubiquitously expressed throughout the human body at relatively low levels.

Transcript Variants
In humans, there is only one known major product of the FAM83H gene.

Paralogs
There are no is_associated_with::paralogs of FAM83H

Orthologs
Below is a table of a variety of is_associated_with::orthologs of the human FAM83H. The table include closely, intermediately and distantly related orthologs.



Orthologs of the human protein FAM83H are listed above in descending order or date of divergence and then ascending order of percent identity. FAM83H is highly conserved throughout all orthologs, this is demonstrated with a 40% identity in the least similar ortholog. FAM83H has evolved slowly and evenly over time.

General Properties
The is_associated_with::molecular weight of FAM83H is 127.1kD and contains 1179 is_associated_with::amino acids. The is_associated_with::isoelectric point is 6.52. There are no significant positive or negative charge clusters in the protein. There is a stretch of 21 0’s from 254-275 and a stretch of 24 0’s from 420-444.1

Composition
FAM83H is is_associated_with::proline rich, being 10.32% protein, and is is_associated_with::asparagine deficient with only 1.1%. The percent composition of each amino acid is fairly consistent throughout the orthologs of the protein. The most distant ortholog displays the most variance in amino acid composition.

Domains
FAM83H has two known domains. The PLDc_FAM83H (is_associated_with::phospholipase like domain) domain stretches from 17-281 on FAM83H. It lacks the functionally important histidine, so while it may share similar structure it most likely lacks PLD activity. The MIP-T3 microtubule binding domain stretches from 909-1176.

is_associated_with::Post-translational modifications
FAM83H is highly phosphorylated post modification. There are 11 predicted phosphorylated sites. There are two motifs with high probability of post translational modification is_associated_with::sumoylation sites. Sumoylation sites are involved in a number of cellular processes, including nuclear-cytosolic transport, transcriptional regulation and protein stability. FAM83H does not have a signal peptide

is_associated_with::Secondary Structure
Fam83H is primarily composed of is_associated_with::alpha helices and random coils. Alpha helices comprise the majority of the protein. There is a transmembrane domain from 231-252.

Subcellular Localization
Protein FAM83H is targeted to the nucleus.

Interacting Proteins
FAM83H was found to interact with is_associated_with::WDR72 and is_associated_with::MMP20. MMP20 is responsible for the breakdown of extracellular matrix and plays a role in tissue remodeling in is_associated_with::ameloblasts. mutations in WDR72 is thought to play a role in is_associated_with::amelogenesis imperfecta

Disease Association
People who suffer from amelogenesis imperfecta have lost function in FAM83H.
