background:
Tomoregulin-1 precursor is a single-pass type I membrane protein thought to be a tumor suppressor in brain cancers. Its expression is down-regulated in these tumors as compared to control brain tissues. In addition, it might also inhibit NODAL and BMP signaling during neural patterning. There are 2 isoforms produced by alternative splicing.
Function:
May inhibit NODAL and BMP signaling during neural patterning (By similarity). May be a tumor suppressor in brain cancers.
Subunit:
May interact with ST14.
Subcellular Location:
Isoform 1: Membrane; Single-pass type I membrane protein. Isoform 2: Membrane; Single-pass type I membrane protein. Isoform 3: Secreted.
Tissue Specificity:
Highly expressed in adult and fetal brain, spinal cord and prostate. Expressed in all brain regions except the pituitary gland, with highest levels in amygdala and corpus callosum. Expressed in the pericryptal myofibroblasts and other stromal cells of normal colonic mucosa. Expressed in prostate carcinoma. Down-regulated in colorectal cancer. Present in Alzheimer disease plaques (at protein level). Isoform 3 is expressed weakly in testis and at high levels in normal and cancerous prostate.
Similarity:
Belongs to the tomoregulin family.
Contains 1 EGF-like domain.
Contains 2 Kazal-like domains.
