YIF1A (Yip1 interacting factor homolog A) belongs to the Yip1p/Yif1p family of proteins, which in humans, contains nine members. YIF1A is the human ortholog of Yif1p, which is a budding yeast protein. It resides in endoplasmic reticulum (ER), ER-Golgi intermediate compartment (ERGIC) and steady state cis-Golgi. This protein has four-five putative transmembrane regions, present at the C-terminal. The molecular weight of this protein is 35.5kDa, and it has a hydrophilic N-terminal, facing the cytoplasm.

All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project and as a result, are supported by the most extensive characterization in the industry.

The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies^® protocols and other useful information.

YIF1A (Yip1 interacting factor homolog A) is a Yip1p interacting protein, with which it forms a heteromeric complex. This complex is essential for the binding of endoplasmic reticulum (ER)-derived vesicles with Bos1p and Sec22p proteins of SNARE complex. It might be involved in maintaining the structure of Golgi apparatus. It is also an interacting partner of vesicle-associated membrane protein (VAMP) associated protein B (VAPB), which is an essential part of the early secretory pathway. Both these proteins play essential roles in ER-Golgi transport, and errors in YIF1A sorting might be a contributing factor to VAPB-associated motor neuron disease. It is also essential for the normal growth of dendrites. It has a ubiquitous expression in the central nervous system (CNS). Studies in mice show that this protein could be one of the factors implicated in amyotrophic lateral sclerosis (ALS).

Prestige Antibodies^® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies^® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:

• IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
• Protein array of 364 human recombinant protein fragments.
