Secondary Information |
|---|
| Presence in other biological fluids/tissue/cells | breast carcinomas, estrogen receptor positive tumors; abundantly expressed in normal
and malignant tissue from the breast, cervix, uterus, ovary,
kidney and prostate; Lower or rare lipophilin B expression
was found in normal colon, pancreas, heart, in gastric and
rectal tumors, and as previously reported in normal testis
and placenta and lung tumors; lipophilin B expression was also detected in the
normal anterior pituitary and pituitary adenomas, in
normal adrenal gland, cartilage, retina, skin,
and salivary gland |
|---|
| Protein Function | Secretoglobins are small, secreted proteins increasingly recognized for their prognostic capacity in a variety of human cancers, though the precise pathophysiologic functions for most members remain to be elucidated |
|---|
| Biochemical Properties | Also known as lipophilin B; small and secretory; dimeric proteins; in breast cancer mammaglobin A and lipophilin B proteins
form a covalent complex, and that the two proteins are
bonded in a head-to-tail orientation; lipophilin
binds PS, PA, or PG preferentially over PC |

| Significance in milk | More in colustrum; role in lipid droplet transport and nutrient delivery |
