when JAK activates STAT, what happens to STAT? |
|
Definition
it is released when phosphorylated, they bind together, enter the cell, and begin transcription. |

Term
what are receptor serine kinase ligands? |
|
Definition
homodimeric peptide ligands held together by cysteine disulfide bonds |

How is TGF beta signaling occuring? |
|
Definition
|
|
Term
what does TGF beta signaling activate? |
|
Definition
members of the SMAD family |
|
|
Term
how is the SMAD protein activated? |
|
Definition
type 2 activates type 1, which then phosphorylates the SMAD protein |

Term
what is the function of the BAMBI |
|
Definition
binding to type 2 receptor, preventing activation of R-SMAD |

|
Term
binding of hedgehog does what? |
|
Definition
inhibits patched, leading to activation of Smoothened and subsequent activation of Gli/Ci |
|
|
Term
what does wnt binding do? |
|
Definition
leads to stabilization of Beta catenin and downstream signaling. |

Term
what is the action of TNF (IL-1) on NFkB |
|
Definition
|
|
Term
explain delta notch signaling |
|
Definition
it directs cell-cell interaction during development.
proteolytic cleavage of the notch goes into the nucleus and activates transcription. |
