Protein Structure

UniProt Annotation

Function

Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components.

Subcellular Localization

Secreted, extracellular space, extracellular matrix, basement membrane. Note=Major component.

Disease Associations

Cardiomyopathy, dilated 1JJ (CMD1JJ) [MIM:615235]: A disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death. {ECO:0000269PubMed:17646580}. Note=The disease is caused by mutations affecting the gene represented in this entry.

Tissue Specificity

In adult, strong expression in heart, lung, ovary small and large intestines, placenta, liver; weak or no expression in skeletal muscle, kidney, pancreas, testis, prostate, brain. High expression in fetal lung and kidney. Expression in fetal and newborn tissues is observed in certain mesenchymal cells in tissues such as smooth muscle and dermis.
