The gene HAT1 (histone acetyltransferase 1) is mapped to human chromosome 2q31.1. It is a key member of HATs. It is an evolutionarily conserved protein and a type B histone acetyltransferase.
Synonyms: Anti-Histone acetyltransferase 1; Anti-KAT1
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)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.

Biochem Physiol Actions: HAT1 (histone acetyltransferase 1) is responsible for histone acetylation, H4K5 (histone 4 lysine 5) and H4K12. MicroRNA miR-486 targets HAT1, thereby inhibiting the expression of ABCA1 (ATP-binding cassette transporter A1). These events suppress cholesterol efflux in THP-1 (human monocytic cell line) macrophages. In esophageal carcinoma, HAT1 is responsible for cell growth. Absence of HAT1 causes G2/M cell cycle arrest, leading to growth inhibition. HAT1 also controls DNA repair by homologous recombination.
