General description

Sad1 and UNC84 domain containing 1 (SUN1) is present in the inner nuclear envelope. It has a C-terminal domain called the SUN domain that is located in the space between the inner and outer nuclear membranes and an N-terminal domain located in the nucleoplasm.

Immunogen

Sad1/unc-84 protein-like 1 recombinant protein epitope signature tag (PrEST)

Application

Anti-SUN1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige. Anti-SUN1 antibody produced in rabbit is also suitable for fluorescent staining.
Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Biochem/physiol Actions

Sad1 and UNC84 domain containing 1 (SUN1) plays an important role in connecting telomeres with the nuclear envelope. It binds to telomere-binding proteins and helps in the formation of the meiotic bouquet. This is a special cluster formed by telomeres at the nuclear envelope and occurs before meiosis I. SUN1 also interacts with SUN2 to form homodimers and heterodimers. This in turn helps in aiding the interaction between the nuclear envelope and the centrosome. It has also been shown that reforming nuclear envelope employs SUN1 to acetylate histones for de-condensation of DNA after mitosis. It is one of the earliest factors to associate with segregated daughter chromosomes in anaphase.

Features and Benefits

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.

Linkage

Corresponding Antigen APREST71107.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
