GH3 cells express receptors for the neuropeptide somatostatin (SRIF). In the present study, we have identified and characterized SRIF1 and SRIF2 receptors in GH3 cells using the radioligands [125I]MK 678 and [125I]CGP 23996. [125I]MK 678 binding to SRIF1 receptors was

Journal of neurochemistry, 59(4), 1241-1250 (1992-10-01)
Somatostatin (SRIF) is a neurotransmitter that produces its multiple effects in the CNS through interactions with membrane-bound receptors. Subtypes of SRIF receptors are found in the CNS that are distinguished by their sensitivities to the cyclic hexapeptide MK-678, such that
J L Martin et al.

Somatostatin receptor subtypes were labeled with the somatostatin analogs [125I]CGP 23996 and [125I]MK 678 and the distribution of these receptors in rat brain was investigated using quantitative autoradiographic techniques. [125I]CGP 23996 and [125I]MK 678 specifically label different populations of somatostatin
