gene
In biology, the word gene (from , ; "...Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a ba ...

The protein encoded by this gene is a member of the
calcium-binding protein Calcium-binding proteins are proteins that participate in calcium cell signalling pathways by binding to Ca2+, the calcium ion that plays an important role in many cellular processes. Calcium-binding proteins have specific domains that bind to calc ...
family. The specific function of this protein has not yet been determined; however this protein is known to interact with DNA-dependent
protein kinase
A protein kinase is a kinase which selectively modifies other proteins by covalently adding phosphates to them (phosphorylation) as opposed to kinases which modify lipids, carbohydrates, or other molecules. Phosphorylation usually results in a fu ...

In biochemistry, a phosphatase is an enzyme that uses water to cleave a phosphoric acid Ester, monoester into a phosphate ion and an Alcohol (chemistry), alcohol. Because a phosphatase enzyme catalysis, catalyzes the hydrolysis of its Substrate ...

DNA-PKcs
DNA-dependent protein kinase, catalytic subunit, also known as DNA-PKcs, is an enzyme that in humans is encoded by the gene designated as ''PRKDC'' or ''XRCC7''. DNA-PKcs belongs to the phosphatidylinositol 3-kinase-related kinase protein family. ...

UBR5
E3 ubiquitin-protein ligase UBR5 is an enzyme that in humans is encoded by the ''UBR5'' gene.
Function
This gene encodes a progestin-induced protein, which belongs to the HECT (homology to E6-AP carboxyl terminus) family. The HECT family protei ...

Integrin beta-3 (β3) or CD61 is a protein that in humans is encoded by the ''ITGB3'' gene. CD61 is a cluster of differentiation found on thrombocytes.
Structure and function
The ITGB3 protein product is the integrin beta chain beta 3. Integrins ...
