WormMine: Gene WBGene00002015

• WormBase Gene ID: WBGene00002015
• Gene Name: hsp-16.1
• Sequence Name: T27E4.8
• Brief Description: hsp-16.1 encodes a 16-kD heat shock protein (HSP) that is a member of the hsp16/hsp20/alphaB-crystallin (HSP16) family of heat shock proteins, and that is identical to the protein encoded by hsp-16.11; an hsp-16.1 reporter fusion, expressed broadly but most strongly in muscle and hypodermis, is induced solely in response to heat shock or other environmental stresses; expression is detectable in somatic tissues in post-gastrulation embryos, all larval stages, and in adults; HSP-16.1 is likely to function as a passive ligand temporarily preventing unfolded proteins from aggregating.
• Organism: Caenorhabditis elegans
• Automated Description: Predicted to enable unfolded protein binding activity. Involved in defense response to Gram-negative bacterium and response to heat. Located in Golgi medial cisterna. Expressed in several structures, including coelomocyte; enteric muscle; intestine; pharynx; and ventral nerve cord.
• Biotype: SO:0001217
• Genetic Position: V :1.9236 ±0.000891

8 Expression Patterns

• Primary Identifier: Expr1381
• Pattern: Expression of both the 48.1C and 41.2C transgenes was consistently observed in embryos from gastrulation onward, in all larval stages and in adults. In postembryonic stages, both transgenes were expressed in most tissues. Although 41.2C is expressed in numerous tissues, especially the pharynx and gut, it is not expressed in the gonad. 41.8C express in a tissue general fashion and expression s in every cell type has been observed in strains carrying this transgene, including neurons, muscle, intestine, and hypodermis. Only the germ-line failed to express this fusion gene. Tissues expressing the hsp-16::lacZ fusion in these strains include nerve ganglia in the head and ventral cord; hypodermal nuclei of the lateral hypodermis, vulva, head and tail, body wall and pharyngeal muscle, somatic gonad, mesodermal tissue such as coelomocytes, and muscles involved in defecation. On the other hand, subtle differences in the expression pattern of these two transgenes were identified. 41.2C stain most intensely throughout the pharynx whereas 48.1C demonstrated conspicuous expression in body wall muscle.

• Primary Identifier: Expr2012617
• Pattern: Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type. Interactive visualizations are available as a web app (https://cello.shinyapps.io/celegans/) and can also be installed as an R package (https://github.com/qinzhu/VisCello.celegans).

• Primary Identifier: Expr10597
• Subcellular Localization: HSP-16.1 shows distinct localization to the medial Golgi of several cell types and is absent from other subcellular sites, including the closely related trans-Golgi and endosomes.

• Primary Identifier: Expr1157862
• Pattern: Developmental gene expression time-course. Raw data can be downloaded from ftp://caltech.wormbase.org/pub/wormbase/datasets-published/hashimshony2015

• Primary Identifier: Expr1384
• Remark: Express condition: after heat shock.
• Pattern: RNA prepared from non-heat-shocked developmental stages did not contain detectable levels of hsp16 mRNA by Northern ananlysis. After heat shock, hsp16 mRNA was at its highest level in the egg and L1 stages, and lowest in adults. At each stage, mRNA for hsp16-2 gene was more abundant than that for hsp16-1 gene, but the difference was greatest in the egg and L1 stages.

• Primary Identifier: Expr15516
• Pattern: Most of the small heat shock protein transgenes did not exhibit detectable signals in the epidermis.

• Primary Identifier: Expr2030853
• Pattern: Single cell embryonic expression.

The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type.
