[https://www.uniprot.org/uniprot/GLRA1_HUMAN GLRA1_HUMAN] Defects in GLRA1 are the cause of hyperekplexia, hereditary, type 1 (HKPX1) [MIM:[https://omim.org/entry/149400 149400]. A neurologic disorder characterized by muscular rigidity of central nervous system origin, particularly in the neonatal period, and by an exaggerated startle response to unexpected acoustic or tactile stimuli.<ref>PMID:8298642</ref> [:]<ref>PMID:7925268</ref> <ref>PMID:7981700</ref> <ref>PMID:7881416</ref> <ref>PMID:7611730</ref> <ref>PMID:8571969</ref> <ref>PMID:8733061</ref> <ref>PMID:9067762</ref> <ref>PMID:10514101</ref> <ref>PMID:9920650</ref>

== Function ==
 +
[https://www.uniprot.org/uniprot/GLRA1_HUMAN GLRA1_HUMAN] The glycine receptor is a neurotransmitter-gated ion channel. Binding of glycine to its receptor increases the chloride conductance and thus produces hyperpolarization (inhibition of neuronal firing).

== Publication Abstract from PubMed ==
 +
The structure and backbone dynamics of an extended second transmembrane segment (TM2e) of the human neuronal glycine receptor alpha(1) subunit in sodium dodecyl sulfate micelles were studied by (1)H and (15)N solution-state NMR. The 28-amino acid segment contained the consensus TM2 domain plus part of the linker between the second and third transmembrane domains. The presence of a well-structured helical region of at least 13 amino acids long and an unstructured region near the linker was evident from the proton chemical shifts and the pattern of midrange nuclear Overhauser effects (NOE). (15)N relaxation rate constants, R(1) and R(2), and (15)N-[(1)H] NOE indicated restricted internal motions in the helical region with NOE values between 0.6 and 0.8. The squared order parameter (S(2)), the effective correlation time for fast internal motions (tau(e)), and the global rotational correlation time (tau(m)) were calculated for all TM2e backbone N-H bonds using the model-free approach. The S(2) values ranged about 0.75-0.86, and the tau(e) values were below 100 ps for most of the residues in the helical region. The tau(m) value, calculated from the dynamics of the helical region, was 5.1 ns. The S(2) values decreased to 0.1, and the tau(e) values sharply increased up to 1.2 ns at the linker near the C-terminus, indicating that the motion of this region is unrestricted. The results suggest a relatively high degree of motional freedom of TM2e in micelles and different propensities of the N- and C-terminal moieties of the transmembrane domain to assume stable helical structures.
