| Description | Crustacean hyperglycemic hormones isoform B precursor [Contains: CHHprecursor-related peptide B (CPRP-B); Crustacean hyperglycemic hormoneB (CHH-B)]. |
| Source organism | Homarus americanus (American lobster) |
| Taxonomical Classification | Eukaryota; Metazoa; Arthropoda; Crustacea; Malacostraca;Eumalacostraca; Eucarida; Decapoda; Pleocyemata; Astacidea;Nephropoidea; Nephropidae; Homarus. |
| Subcellular location | Secreted protein |
| Developmental Stage | N/A |
| Similarity | Belongs to the arthropod CHH/MIH/GIH/VIH hormone family. |
| Tissue Specificity | Produced by the medulla terminalis X-organ in the eyestalks and transported to the sinus gland where they are stored and released. Present also in the ventral nervous system |
| Post translational modification | Stereoinversion of L-Phe (form CHH-B-I) to D-Phe (form CHH-B- II). |
| Function | Hormone found in the sinus gland of isopods and decapods which controls the blood sugar level. Has a secretagogue action over the amylase released from the midgut gland. May act as a stress hormone and may be involved in the control of molting and reproduction |
