General annotation (Comments)

Function	Although its physiological function is unclear, it can inhibit neutrophil cathepsin G and mast cell chymase, both of which can convert angiotensin-1 to the active angiotensin-2. Ref.14
Subunit structure	Interacts with DNAJC1. Ref.18
Subcellular location	Secreted.
Tissue specificity	Plasma. Synthesized in the liver. Like the related alpha-1-antitrypsin, its concentration increases in the acute phase of inflammation or infection. Found in the amyloid plaques from the hippocampus of Alzheimer disease brains. Ref.7 Ref.8
Domain	The reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the carboxyl group of the serpin reactive site and the serine hydroxyl of the protease. The resulting inactive serpin-protease complex is highly stable.
Miscellaneous	Alpha-1-antichymotrypsin can bind DNA.
Sequence similarities	Belongs to the serpin family.
Caution	It is uncertain whether Met-1 or Met-4 is the initiator.
Sequence caution	The sequence AAA51543.1 differs from that shown. Reason: Frameshift at positions 101, 106, 111, 117, 123, 129 and 421. The sequence AAT08029.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. The sequence AAT08029.1 differs from that shown. Reason: Frameshift at position 4. The sequence BAD92297.1 differs from that shown. Reason: Erroneous initiation. The sequence CAA48671.1 differs from that shown. Reason: Erroneous initiation.
