UniProt ID

Function

In adipose tissue and heart, it primarily hydrolyzes stored triglycerides to free fatty acids, while in steroidogenic tissues, it principally converts cholesteryl esters to free cholesterol for steroid hormone production.

Summary

Hormone-sensitive lipase (HSL) is a key enzyme in fatty acid mobilization, overall energy homeostasis, and possibly steroidogenesis. It is acutely controlled through reversible phosphorylation by catecholamines and insulin (1). HSL is the rate-limiting enzyme in hydrolysis of triglycerides in adipose tissue and of cholesteryl esters in steroidogenic tissues including the adrenals, ovaries, testes, and macrophages (2, 3). HSL activity has been positively correlated with free and esterified cholesterol ratios in seminiferous tubules (STf) and interstitial tissue (ITf) enriched fractions, but not with triglyceride levels, during testicular development. HSL is localized to elongated spermatids and Sertoli cells, where its distribution is stage-dependent, and within the cells lining the excurrent ducts of the testis. The HSL protein levels and enzymatic activity in ITf and STf were reported positively correlated with serum testosterone levels during development (4).

Form

50 mM Tris-Glycine (pH 7.4), 0.15 M NaCl, 40% Glycerol, 0.01% sodium azide and 0.05% BSA.

Storage & Stability
