TRPM3 in temperature sensing and beyond
TRPM3, also known as melastatin 2 (MLSN2), LTRPC3 (long TRPC3) and KIAA1616, is a member of the TRPM subfamily of transient receptor potential (TRP) ion channels. The channel was originally identified as a volume-regulated ion channel that can be activated upon reduction of the extracellular osmolality. Later, the channel was proposed to be involved in the modulation of insulin release in pancr...
متن کاملTRPM3 Is a Nociceptor Channel Involved in the Detection of Noxious Heat
Transient receptor potential melastatin-3 (TRPM3) is a broadly expressed Ca(2+)-permeable nonselective cation channel. Previous work has demonstrated robust activation of TRPM3 by the neuroactive steroid pregnenolone sulfate (PS), but its in vivo gating mechanisms and functions remained poorly understood. Here, we provide evidence that TRPM3 functions as a chemo- and thermosensor in the somatos...
متن کاملTRPM3, a biophysical enigma?
TRPM3 [TRP (transient receptor potential) melastatin 3] is one of the least investigated proteins of the TRP family of ion channels. Heterologously expressed TRPM3 channels are constitutively active, have an outwardly rectifying current-voltage relationship and are inhibited by intracellular Mg(2+) ions. Besides these rather common features, in which TRPM3 channels resemble the closely related ...
متن کاملTRPM3 Expression in Mouse Retina
Transient receptor potential (TRP) channels constitute a large family of cation permeable ion channels that serve crucial functions in sensory systems by transducing environmental changes into cellular voltage and calcium signals. Within the retina, two closely related members of the melastatin TRP family, TRPM1 and TRPM3, are highly expressed. TRPM1 has been shown to be required for the depola...
متن کاملSensing the Heat Stress by Mammalian Cells
BACKGROUND The heat-shock response network controls the adaptation and survival of the cell against environmental stress. This network is highly conserved and is connected with many other signaling pathways. A key element of the heat-shock network is the heat-shock transcription factor-1 (HSF), which is transiently activated by elevated temperatures. HSF translocates to the nucleus upon elevate...
