Pitx1 | Pituitary homeobox 1; Sequence-specific transcription factor that binds gene promoters and activates their transcription. May play a role in the development of anterior structures, and in particular, the brain and facies and in specifying the identity or structure of hindlimb. Can independently activate and synergize with PIT-1 on pituitary-specific target gene promoters, thus may subserve functions in generating both precursor and specific cell phenotypes in the anterior pituitary gland and in several other organs. Can activate pituitary transcription of the proopiomelanocortin gene. (315 aa) | ||||
Serpinb1b | Leukocyte elastase inhibitor B; Regulates the activity of the neutrophil proteases. Forms only a stable complex with CTSG/Cathepsin G. During inflammation, limits the activity of inflammatory caspases CASP1 and CASP4 by suppressing their caspase-recruitment domain (CARD) oligomerization and enzymatic activation. Belongs to the serpin family. Ov-serpin subfamily. (382 aa) |
