ZRANB2
Zinc finger Ran-binding domain-containing protein 2 is a protein that in humans is encoded by the ''ZRANB2'' gene. Interactions ZRANB2 has been shown to interact with U2 small nuclear RNA auxiliary factor 1 and SNRP70 snRNP70 also known as U1 small nuclear ribonucleoprotein 70 kDa is a protein that in humans is encoded by the ''SNRNP70'' gene. snRNP70 is a small nuclear ribonucleoprotein that associates with U1 spliceosomal RNA, forming the U1snRNP a core comp ....

U2 Small Nuclear RNA Auxiliary Factor 1
Splicing factor U2AF 35 kDa subunit is a protein that in humans is encoded by the ''U2AF1'' gene. Function This gene belongs to the splicing factor SR family of genes . U2AF1 is a subunit of the U2 Auxiliary Factor complex alongside a larger subunit, U2AF2. U2AF1 is a non-snRNP protein required for the binding of U2 snRNP to the pre-mRNA branch site. This gene encodes a small (~35 kDa) subunit which plays a critical role in RNA splicing by recognizing and binding to AG nucleotides at the 3’ splice site to facilitate spliceosome assembly. Alternatively spliced transcript variants encoding different isoforms have been identified . Somatic mutations in ''U2AF1'' have been found in a range of human cancers, with a distinctive pattern of these mutations at the zinc fingers implicating a functional role under selection. In lung cancers, these mutations affect alternative splicing of several transcripts, including oncogenic ROS1 fusions. U2af1 conditional deletion in mouse hematopoi ...

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid resid ...

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 basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as g ...
