General annotation (Comments)
| Function | Its binding to fibronectin and some other ligands is calcium dependent. |
| Subunit structure | Homotrimer; disulfide-linked. Interacts with LAMA2 By similarity. |
| Subcellular location | |
| Tissue specificity | Component of both basement membranes and other connective tissues. Expressed in heart, placenta and ovary. |
| Developmental stage | Widely expressed during embryonic development. Primarily detected within the neuropithelium, spinal ganglia and peripheral nerves. Ref.5 |
| Post-translational modification | O-glycosylated with core 1 or possibly core 8 glycans. It is unsure if the O-glycosylation is on Thr-347 or Ser-348. Ref.8 |
