The team also found that antibodies to human
surfactant proteins called SP - A and SP - B reacted with proteins taken from the fish, implying that both use the same «anti-glue» to keep their lungs open.
«Our study provides compelling evidence that the fetus regulates the timing of its birth, and that this control occurs after these two gene regulatory proteins − SRC - 1 and SRC - 2 − increase the production of surfactant components,
surfactant protein A and platelet activating factor,» said senior author Dr. Carole Mendelson, Professor of Biochemistry, and Obstetrics and Gynecology at UT Southwestern.
UT Southwestern researchers found that the proteins SRC - 1 and SRC - 2 activate genes inside the fetus» lungs near full term, resulting in an increased production of surfactant components,
surfactant protein A (SP - A), and platelet - activating factor (PAF).
For example, they found also accelerated adaptation for a gene encoding a lung
surfactant protein (SFTPB), which may have been due to lung changes necessary for diving.
Importantly, patients with mutations in a single copy of NKX2.1 often have Brain - Lung - Thyroid Syndrome, which is characterized by respiratory distress after birth and accompanied by decreased
surfactant protein expression.

Type I cells form the gas diffusing barrier and type II produce a mixture of lipids and

Mendelson made the finding while studying lung

Basic biological compartmentalisation is a key property of artificial cells and existing solutions are found in self - assembled amphiphiles, polymers, inorganic molecules and
protein -
surfactant conjugates which form membrane delineated aqueous droplets, however the interior of these compartments are typically homogeneous and therefore do not mimic the crowded heterogeneous cytoplasm of natural cells.
Prevents chromosomes from collapsing into a single chromatin mass by forming a steric and electrostatic charge barrier: the
protein has a high net electrical charge and acts as a
surfactant, dispersing chromosomes and enabling independent chromosome motility (PubMed: 27362226).
