Tissue Specificity[Alpha-1-microglobulin]: Expressed by the liver and secreted in plasma. Occurs in many physiological fluids including plasma, urine, and cerebrospinal fluid (PubMed:11877257). Expressed in epidermal keratinocytes, in dermis and epidermal-dermal junction (at protein level) (PubMed:22096585). Expressed in red blood cells (at protein level) (PubMed:32092412). Expressed in placenta (PubMed:21356557). {ECO:0000269|PubMed:11877257, ECO:0000269|PubMed:21356557, ECO:0000269|PubMed:22096585, ECO:0000269|PubMed:32092412}.;
[Inter-alpha-trypsin inhibitor light chain]: Expressed in airway epithelium and submucosal gland (at protein level). Colocalizes with TNFAIP6 at the ciliary border. Present in bronchoalveolar lavage fluid (at protein level). {ECO:0000269|PubMed:16873769}.

Peripheral membrane protein {ECO:0000305|PubMed:22096585}. Mitochondrion inner membrane {ECO:0000305|PubMed:23157686};
Peripheral membrane protein {ECO:0000305|PubMed:23157686}. Secreted, extracellular space, extracellular matrix {ECO:0000269|PubMed:22096585}. Note=The cellular uptake occurs via a non-endocytotic pathway and allows for localization to various membrane structures. A specific binding to plasma membrane suggests the presence of a cell receptor, yet to be identified. Directly binds collagen fibers type I. {ECO:0000269|PubMed:22096585}.
