Fc-receptor molecules tend to have short cytoplasmic tails.How does this influence signaling events within the Fc-receptor cell?

Question

Quizplus · Accepted Answer

Fc-receptors have short cytoplasmic tails and thus rely on associated molecules, such as ITAMs (Immunoreceptor Tyrosine-based Activation Motifs) or ITIMs (Immunoreceptor Tyrosine-based Inhibitory Motifs), to initiate signaling cascades within the cell. These coreceptors are crucial for transmitting the signal from the engaged Fc-receptor into the cell, leading to various cellular responses.
