Human expression is seen most predominately in parathyroid, muscle, ear, eye, mammary gland, lymph node, thymus in addition to 27 other tissues. KIAA1109 is also expressed in various disease states including 12 different tumors as well as bladder carcinoma, chondrosarcoma, glioma, leukemia, lymphoma, non-neoplasia, retinoblastoma tissues.[11] KIAA1109 is expressed in all stages of development from embryoid body to adult, except in infants. No expression of my gene is seen during the infant stage of development.[11]

Protein
General Properties
KIAA1109 protein is 5005 amino acids in length,[17] and has a predicted molecular weight of 555519.38 daltons.[18] The isoelectirc point of KIAA1109 protein is predicted to be 6.12.[19]
Composition
The amino acid composition of KIAA1109 protein showed amino acid frequencies within 1.5% of that of normal human proteins for all but Alanine, Serine and Threonine. Alanine has a lower frequency in KIAA1109 than in that of a normal human protein while Serine and Threonine both have a higher frequency in KIAA1109 than in the average human protein.[20]
Conservation
The amino acid sequence of KIAA1109 is highly conserved throughout mammals. The protein identity ranges from 93.2% in Opossum to 99.8% in Chimpanzees and protein similarity is no less than 97% in all mammals included. Birds continue to show fairly high conservation with protein identities around 90% and proteins similarities at a high 96%. While conservation is still high the lower numbers may be due to small truncations on either, the 5’ and 3’ ends of these sequences.[13]
As we move to the more distant species of zebra fish and then the red four beetle and carpenter ant the conservations drops. In the insects the protein identities are down to around 34%.[13]

Conserved Domains
NCBI conserved domains search identified two domains in KIAA1109. The first is the fragile site associated C-terminus, which is said to be linked to celiac disease susceptibility according to genome-wide-association studies and may also be associated with polycystic kidney disease.[21] The second conserved region identified by NCBI in KIAA1109 is an uncharacterized conserved protein (DUF2246), whose function is unknown and is conserved in various species from humans to worms.[22]
Post Translation Modifications
KIAA1109 is predicted to undergo various types of post translational modifications including glycate, N-glycosylation, O-GlcNAc, O Glycosylation, Sulfonation and Phosphorylation.[23]
Subcellular Localization
KIAA1109 contains one transmembrane domain from amino acids 26-46.[17] No signal peptides, mitochondrial targeting sequences or chloroplast peptides were predicted for my protein and it is therefore not predicted to localize to secretory pathway, mitochondria or chloroplast.[24]
Interacting Proteins
MADH2 and Beta-catenin were both found to have a physical interaction with my protein as deteched by display technonloy by Miyamoto-Sato et al. 2010.[25][26]
