Smelling hair in a dream is a message of secrets. To be enjoying the aroma of hair may mean exciting and happy secrets that you will derive pleasure from. To be dreaming of foul-smelling hair implies secrets you would rather not hear and that you are not obligated to keep.
Ras Pathway. Ras is a membrane-associated guanine nucleotide-binding protein that is normally activated in response to the binding of extracellular signals, such as growth factors, RTKs (Receptor Tyrosine Kinases), TCR (T-Cell Receptors) and PMA (Phorbol-12 Myristate-13 Acetate).
BRAF belongs to a family of serine-threonine that includes ARAF, BRAF, and CRAF (RAF1). RAF are central mediators in the MAP signaling cascade and exert their effect predominantly through and activation of MEK. This occurs following the (hetero- or homo-) of the RAF molecules.
