General annotation (Comments)
| Function | May play a role in the regulation of hemostasis. The soluble form may have inhibitory properties towards coagulation factors. May interact with cellular G-protein signaling pathways. May bind to the DNA 5'-GTCACATG-3'(CDEI box). Inhibits trypsin, chymotrypsin, plasmin, factor XIA and plasma and glandular kallikrein. Modulates the Cu/Zn nitric oxide-catalyzed autodegradation of GPC1 heparan sulfate side chains in fibroblasts By similarity. Ref.7 |
| Subunit structure | Interacts with CPEB1. Interacts (via NPXY motif) with DAB2 (via PID domain); the interaction is impaired by tyrosine phosphorylation of the NPXY motif By similarity. |
| Subcellular location | Cell membrane; Single-pass type I membrane protein Potential. Nucleus Potential. |
| Tissue specificity | Expressed in placenta, brain, heart, lung, liver, kidney and endothelial tissues. |
| Post-translational modification | The BPTI/Kunitz inhibitor domain is O-glycosylated. Ref.7 |
| Sequence similarities | Belongs to the APP family. Contains 1 BPTI/Kunitz inhibitor domain. |
