Fc-receptor molecules tend to have short cytoplasmic tails. How does this influence signaling events within the Fc-receptor cell?
A. The Fc receptor is adjacent to secondary messengers (e.g., MAP kinase) that translocate into the nucleus to affect transcription.
B. The Fc receptor is dependent upon a co-receptor (e.g., ITAM or ITIM) that will trigger signaling events within the cell.
C. The Fc receptor is not directly involved in a signaling event.
D. The Fc receptor serves only to enhance or dampen a signaling event.
E. The Fc receptor translocates into the cytoplasm where it will binding to secondary messengers.
