The function of the protein in the human body is that it is required for the structure, regulation, and function of the tissues and organs of the body. (Image will be Uploaded soon) The structure of a protein is a 3-dimensional arrangement of amino acid residues that link up to form polypeptide chains. Proteins are polymers whose structure is formed by the link-up of several such long chains that are made from amino acid (monomer of protein) sequences.

Mucin short variant S1, also called polymorphic epithelial mucin (PEM) or epithelial membrane antigen (EMA), is a mucin encoded by the MUC1 gene in humans. Mucin short variant S1 is a glycoprotein with extensive O-linked glycosylation of its extracellular domain. Mucins line the apical surface of epithelial cells in the lungs, stomach, intestines, eyes and several other organs.

Vps15 contains multiple WD repeats and also binds to Gpa1 preferentially in the GDP-bound state; these observations led us to hypothesize that Vps15 may function as a G protein β subunit at the endosome. Here we show an X-ray crystal structure of the Vps15 WD domain that reveals a seven-bladed propeller resembling that of typical Gβ subunits.
